Follow On-Screen Instructions - Not yet documented weapon: Press "b" to launch a proximity Bomb. The game rewards strategy and careful attention to orbits, aiming, and gravity - which affects your ship and the flight of your Photon Torpedoes.
ED-II adds a targeting marker that makes your ship much more deadly, as well as the new Proximity Bomb - which launches slowly and carries the Ship's velocity plus a launch velocity. The Bomb is effected by Gravity (of course) and is Strongly attracted to the Alien ship. Fixed some minor bugs: - score now resets on pressing "P" for a new game - end sequence more dramatic
