This is a great port of the arcade game of Space Invaders. The bugs from the original version INV appear to have been fixed. It plays and sounds more like the arcade version. I wish this would have been the original port of Space Invaders back so many years ago. This would have been considered the classic version.

Inv+ is all about aliens invading from space, and as always, you have to shoot every last one of them before they shoot you or land on your planet. But this time, there are more of them than ever!

Inv+ is a different take on the homebrew Space Invaders concept, where instead of trying to accurately re-create the look of the original arcade game, the focus is more on re-creating the gameplay and feel of it. The end result is the only 2600 invader game with all 55 aliens on screen. The way the graphics are handled keeps the aliens small and in proportion with the screen, but it also looks very blocky with each alien being only two rather chunky pixels wide. Obviously, this severely limits any sort of detail, but once you get past the looks, the game plays pretty well. The speed of the aliens feels right, the UFO scoring is patterned after the arcade version, plus there's a simultaneous two-player option and an invisible invaders mode. In the end, Inv+ does a good job of putting up a lot of enemies on screen and making it work. It's still basically just Space Invaders, but it manages to do that pretty well - if you can look past the blocky graphics.

GREAT take on Space Invaders while the "invaders" are simple blocks in this version there are 55 of them in 11 rows just like in the arcade game and the "shot counting" trick from the arcade game works in this version as well! If you like the coin-op you will love this game. Much more challenging than the original Atari version of SI. There is a big difference between shooting 36 invaders per screen and shooting 55. Excellent game.

I've played this game over and over again!!!! I can't believe how true to the arcade version this cart really is. The graphics and sound are just awsome. It was well worth the wait!!! great job guys !
