Surround'EM is one of my latest games made for the Atari 400/800/600XL,800XL,1200XL,65XE,130XE,XEGS. Port will be soon available for the Atari 5200. This is based on Surround and Slither. I originally wanted to make a multi-game cartridge including surround as one of the games, but decided to make a game that has options to play several similar games.
The Game options allow you to play the standard surround game facing multiple computer opponents, sometime obstacles are present in upper levels. Can have the border walls on or off, or have extra walls in the center. Can select 45 or 90 degree turns, if your fire button controls the speed, or have it start slow and progressively speed up during each round.
The a growing slither game is based on the Vic-20 Slither, but has fruits that move around the screen and throws in random obstacles. Each fruit rewards some points and your snake grows a few units.
The dodge Obstacles Survival game is based on an old game I made years ago called Dodge Survival where you simply have to move around avoiding obstacles as long as possible, points are awarded each second you survive.
There is a bonus rescue space man web rescue game that you need to collect spacesuits from aliens building a web around the screen. They are moving diagonally around the screen. This was added by a suggestion from Video 61 because he seen the development tests of the game routines, and the way it look reminded him of the Star Trek episode "The Tholian Web"
On the standard XL/XE machines, 2 players can play multiplayer. 400/800 and Multijoy8 can allow up to 4 players. Those are separate options under the title screen. This is my first game I done to support more than 2 players either using the 2 extra joystick ports on the 400/800 or the Multijoy8.
