big tanks in a small package
Atomic Tanks is a game in which you control an overly-powerful tank and attempt to blow up other highly powerful tanks. Players get to select a number of weapons and defensive items and then attack each other in a turn-based manner. The last tank standing is the winner.
Atomic Tanks Portable works best with the PortableApps.com Platform
Atomic tanks is a multi-platform Scorched Earth clone similar to the Worms™ series of games. Annihilate the other tanks to earn money, then spend it on bigger and better shields and weapons to wipe out the opposition. It features a wide array of weapons, AI players, destructible landscape, weather, parachutes, teleports and a wide range of other features.
You can also read the Atomic Tanks documentation.
Custom Background Image: Atomic Tanks now supports a custom background image. On the Graphic menu under Options, turn on Custom Background. Then save a bitmap of your choice in the AtomicTanksPortable\Data\settings\.atanks folder. The image should be in bitmap (.bmp) format and it'll help if the size of the bitmap is the same as your Atomic Tanks resolution. By default this is 800x600.
