Frenzy - Atari 7800



Trapped in a bizarre, alien high-tech structure and surrounded by robots, your Humanoid moves from cell to cell as you face a band of deadly mechanical monsters. Odd marching skeletons clunk toward you. Robotic tanks trundle into position. Face your enemy and fire, or be doomed by their fatal touch! Eliminate all automatons and proceed to the next assembly.

Stay alert! Your enemies now fire deadly blasts. In Berzerk, all walls absorb shots from you or the robots. In Frenzy, some cell walls ricochet the blasts--both yours and the robots--so watch where you fire! Worst of all is Evil Otto, the bouncing menace who passes through walls and destroys any creature on contact. It's a bizarre battle for survival as Evil Otto bounces toward you! Will you make it?

Atari 7800 veteran Bob Decrescenzo brings arcade classics Frenzy and Berzerk home to the 7800, complete with all the details you'll find in the arcade games. Both games are reproduced with careful attention to detail to match their arcade counterparts as closely as possible. The original speech from the arcade that helped make both games so memorable is also included!

For a new challenge, there are two-player cooperative and competitive gameplay modes. In cooperative modes, both players try to achieve a single high score and share six lives. In two-player competitive mode, each player has their own set of scores and lives. In competitive mode, you even get points for shooting your opponent!

I love this port! Voices are great, having both games, and CoOp! This shows off the 7800 and works on the 2600 (with updates)

Just got my copy last night and I couldn't put it down. The game play is excellent. Really loved the detailed manual. This is by far the best version of this game I have ever seen on a console and has far exceeded my expectations.
Dan Wolak on 06/26/2023 08:23pm
You get two terrific games for the price of one here! Frenzy and Berzerk. Berzerk is a classic, and if you don't have a 2600 cartridge, you should get this. Actually, even if you have the 2600 cart, still get this! It adds simultaneous co-op or competition play and the voice of Evil Otto! Frenzy is a great sequel and adds some new features to the robot shooter.

This is a great game
I like it how it have two games in one
Great job

My favorite arcade game of all time is Berzerk. I had only played Frenzy back in the day a few times and several times recently at a retro arcade. Being the sequel of Berzerk of course I was always intrigued. Berzerk for the Atari 2600 was good for its time. This home brew is therefore extremely fulfilling and a proud part of my collection. So much arcade goodness in one cartridge!
Rob Adams on 06/01/2021 12:07pm
Absolutely AWESOME! Great sound and game play, makes the original Berzerk for 2600 look pitiful. Beware Evil Otto is ALOT faster than expected!! A definite must have for the 7800 collection and is one of my favorite games. You will have nonstop entertainment for hours. Hats off to the designer for the addition of Berzerk on cartridge and the box art work is excellent as well.

First off I always loved Berzerk on the 2600. It was one of my favorite games on the console as a kid. I could play it for hours and just have so many great memories of playing it. This game, both "Frenzy" and "Berzerk" are just amazing and so much fun to play. I highly recommend this game to anyone who loved playing Berzerk on the 2600.
Aaron Clark on 05/26/2019 01:29am
I never had the opportunity to play "Berzerk" or "Frenzy" in the arcade. This game is fantastic and quickly became one of my favorites in my collection. I have two complaints.

1. The bullets can be nearly impossible to see sometimes.

2. I keep finding myself playing "just one more game" to beat that last high score. again and again and again and again.

This game is a must have for any 7800 fan!

I really enjoyed this game. The 2 player co-op mode is amazing. My friends and I tend to focus on trying to shoot each other, which could and should be its own game. I would love to see a modern Laser Tag game based on Frenzy. Imagine 8 players battling in randomized arenas, or teams of 4 on 4. Or even an "assassin" mode where you are assigned a player to "assassinate", and once you succeed you take on their assigned target, all while avoiding your assassin. Somebody make this happen. I'll throw 5 bucks toward the project.
Derek L on 01/16/2018 08:44pm
I am so glad that I bought this game. The manual was a very nice touch that I did not expect when I received this game. When I received this package, I was blown away with nostalgia. Since Frenzy was originally only ported to the ColecoVision I thought it was great to be able to play it on an Atari 7800. Not only is Frenzy included on the cartridge but a near arcade perfect version of Berzerk(which I prefer) with voice is included as a bonus. I ordered this along with the Pac-Man Collection and highly recommend both of them. I will order some more games in the future!

This a good, but not great version of the Stern arcade game. That said, I don't know how much better you could do with the hardware, but there are a few things that really limit my enjoyment of the game.

My biggest gripe is that the breakable walls are not colored differently than the non-breakable ones like in the arcade game. It makes it hard to differentiate the two when things get hectic. Again, maybe there is a legitimate hardware limitation to blame for this, I don't know.

Secondly, the hit detection on the skinnier enemy types is a little off when shooting them from directly above or below. I can't tell you how frustrating it is to nail one right in the skull and have it just pass through. There doesn't seem to be a surefire way to eliminate these enemies from this angle. In an already difficult game, adding this handicap makes for some very frustrating moments.

The game also suffers some pretty significant slowdown when the screen is full of enemies, but I can let that slide a little bit given the hardware.

If you know not to expect perfection, this is a worthwhile cart to have in the collection, but there are far better arcade ports for the 7800.

The addition of Berzerk and some extra modes is a nice touch, but I just can't feel like I should enjoy it more than I do. The original Frenzy is a five star game, but this port isn't quite as stellar.
Joel Ressler on 09/03/2017 03:44pm
My score of 4 is for the Berzerk game. I loved this game as a kid, and it's still fun. Control is tight and the synthetic voice is amazing. I can't remember the original well enough to know if my complaint is against this port or the original arcade game, but there is one thing that frustrates me. Your character moves so slow compared to the speed of the enemies' shots, it's hard to get out of the way, and if you and the enemies spawn need each other, you are pretty much doomed from the start. Still, it's a very fun and challenging game.

I'd give Frenzy a 3 if I could rate it separately. My issue with Berzerk is back, but with several more to add. The enemies are very skinny so if you're trying to shoot them from above or below, they are a very small target. And on many levels there's too many enemies! For me, it's too frustrating to be fun.
Funkmaster V on 07/17/2017 07:29pm
Hey kids, I love this game. And there are plenty of reviews singing the praises of it. But unfortunately I have a major problem with it: several stages features robots and colors THAT ARE ALMOST IMPPOSSIBLE TO SEE on my TV's. I've tried 3 TV's. and especially the dark red robots, especially the bullets. are almost invisible. Still. TONS O FUN to be had. just be warned.

First time I played Berzerk was at the local Pizzeria in my neighborhood. I think I recall seeing a Frenzy cab once at the Nathan's close to where I lived at the time, but never played on an actual arcade cabinet.

My first experience with Frenzy was on the ColecoVision emulator ColemDOS during the mid-90's. It was missing from my original cartridge collection in the 80's. Throughout the years though, I have racked up some considerable game time via MAME for the Arcade game and AtariMax cart on my ColecoVision, as well as through emulation for the console. I have had a good taste of the game, Frenzy.

The Atari 7800 port is quite excellent. The higher 320 resolution mode is utilized and the game really shines. All A.I. behavior was carefully ported over including nuances of corner and ricochet shots. Interactive maze elements are present: Big Otto - check. Central Computer - check. Power Plant - check. Robot Factory - check.

The variety of modes are fantastic just like some of the 7800's excellent retail arcade ports such as Joust and Centipede. Meaning one and two players (alternating) modes, of course are present; additionally, the two player cooperative and competitive is where it really gets interesting for the two-player modes.

Frenzy under the 7800 in its own right goes above and beyond in being a fantastic port; however, we are only halfway through the greatness contained on the cartridge, as Berzerk is present as well in all its glory too. Although a simpler game than Frenzy, Berzerk is my preferred choice between the two (Insert stronger nostalgic factor here).

Berzerk is playing second fiddle to no one and the differences as would be experienced in the Arcade are all present here as well. While walls are either of a reflective or can be shot away under Frenzy, in Berzerk they are just deadly to the touch.

There are different Ottos too. Berzerk's is just flat out 'Evil' and indestructible, while Frenzy's is 'Crazy', can be destroyed, but will re-materialize with a vengeance.

So, play with two players as a team, as enemies, or take the robots (/skeletons/tanks) on solo, enjoy speech similar to their Arcade counterparts, and enjoy having Frenzy (and Berzerk) as an excellent addition to the 7800 library.

Growing up the only system I had was the Atari 7800 up until I was 18 years old. I am 43 now and if played Berserk a lot. If someone had told me a 7800 could run not only Frenzy but Berserk with voice I wouldn't have believed you. Now I just need to figure out how to mail it to myself in 1984!!!
Inky on 05/11/2016 08:19am
I don't buy a lot of homebrews - in fact I only own three - but I happily added this one to my collection. It has a very faithful translation of the acrcde game Frenzy, complete with all the bells and whistles, and as an added bonus, it has Berzerk! Oh, and it has VOICE as well! Yet another PacManPlus classic!
Jay on 04/08/2015 07:46pm
This game was my first purchase from AtariAge, and it was a good one. I loved the old Berzerk, and this cartridge allows that to be played as well. I also love the robotic voice when Otto appears. It's almost spooky in a way. The game plays great and I noticed no glitches or anything whatsoever. I highly recommend this title to anyone who loves the old Berzerk.
Oliverqu33n on 03/15/2015 11:34am
I wasn't sure when I bought this if it would be great or not. I am a big fan of the both Berzerk and Frenzy, the arcade games, and the original 2600 Berzerk port. I'm also pretty hesitant to buy most homebrews, but given that I was such a fan of the game, I gave it a shot.

I can I say this was a great buy. I especially am glad that I own the boxed version. The manual and box quality are top notch. I'm also very fond of the port. They even got the voice working without a Pokey Audio Chip! That's impressive in itself, but even better than that, it really feels like the arcade version. It's a little slower, but all in all it's the most faithful port I've seen.

Adding in Berzerk was another great addition. Berzerk is the game I played the most outside of Pitfall II on the 2600, and I'm quite happy with this port. I wish the games played just a little faster, but I can't really say anything negative about this port.

Really, my recommendation is that you buy this game immediately. If you're not up for spending the money on the box and manual, it is available in cart only form now for $30. Either way, you won't be disappointed.
dauber on 01/07/2015 12:58pm
Okay, I admit it...I didn't follow ANY of the thread on the 7800 forum about this cart...but yet, I figured because it was a Bob game, I couldn't POSSIBLY go wrong.

Yet, somehow I did go wrong...BY NOT BUYING IT SOONER THAN I DID!

Holy crap, ARE YOU KIDDING ME??? Voice effects on the TIA chip?!? (I know it's not the POKEY because I did an A/V mod that unintentionally turned my POKEY volume almost all the way down and TIA volume all the way up!)

ARE YOU KIDDING ME??? THE OPENING TUNE?!?! (I won't spoil it for those who haven't bought it, but good God....good freakin' God!! Some people will instantly recognize it from....somewhere. :) )

As usual, excellent conversion!
Uberarcade on 07/10/2014 08:33am
This has become one of my favorite games on the 7800. It is a great game to have on the 7800 and feels like something that belonged there all along. Plays perfect. Amazing job on the conversion. Everybody should own this cart.
Mark Godau on 06/03/2014 07:24pm
I just received this cartridge yesterday and I can't stop playing! This adaptation is outstanding. I purchased the cart mainly to get Berzerk and the cartridge does not disappoint. The gameplay is what I remember from my arcade days back in the 80's. The extras such as the spoken parts complete the experience that was missing on my old 2600 Berzerk cart. I don't remember Frenzy being in any of my old arcades, but this is a fun game as well. Back in the day I fed many a quarter into Berzerk and I'm pretty sure this cart has already paid for itself. Great job Bob, keep these classics coming!
Mark Botelho on 01/14/2014 10:00am
Great Job on this one Bob / AtariAge. Having both Berzerk and Frenzy on one cart blows me away. Such a great Arcade shooter done right. GORF should be next on the list. Another classic shooter that needs to be done right for a home console. Thanks Again
Mark Botelho on 01/14/2014 09:57am
Absolute awesome game. Both Frenzy and Berzerk game play pretty spot on with the arcade versions. This game is definitely my favorite for any atari system. The fact that both games are on one cart blows me away. Great Job Bob,you should think about making a GORF for the 7800. Another great shooter that has been butchered by home consoles.
Dan Vaughn on 11/04/2013 02:45pm
I was a 10 year old kid, growing up in a small town, when video games started showing up - the year was 1980. To say they left an impression would be an understatement. I have a clarity of memory for "Golden Age" video games, that is unparalleled by the average guy or gal. This is why, as far as video game "arm chair quarterback's" go, I am more critical than most.

Therefore, let it be known, that this is the first time, I have nothing negative to say about a homebrew video game. "Frenzy" (to put it 80's style) is AWESOME!!!

In addition, you also get "Berzerk" on this cartridge, which is equally well done. I really appreciate Bob DeCrescenzo for adding "Berzerk", because it is actually my favorite.

I don't have anything more to say - which is record for me as I usually don't shut up! Yes, this game is that good!
