ZAP is a team-based Internet multiplayer game with 2D retro-style vector graphics. The control scheme is patterned after the arcade classic Robotron. It uses the Torque Network Library for its network transport layer. It supports multiple game types (Capture the Flag, Soccer, Football, Hunters, Rabbit, Zapmatch), configurable ship powers, and support for voice recording and gamepad controllers (not on all platforms).
Bastet ("bastard tetris") is an ncurses Tetris clone which is harder than every other tetris released. It is based on a heuristics engine which tries to detect which block you need or don't need, and then gives you the blocks that you don't need. For instance, if you usually play by leaving long "canyons" one square wide and then waiting for the long "I" block, you'll have to wait till eternity before you see it. The heuristics have been worked on for some time and are quite nasty.
Tanky is a tank shooting game with old-school graphics (lines and flying pixels in 16 colors). It can be played by 2-3 players on one keyboard. The main goal is to shoot your opponents down. You have one tank, five shots, and a shield which can take five points of damage. Every time, there are different bonuses flashing around. Collect them and gain faster weapons, more shots, recharge your shield, etc. The best-scored player wins.
