Invasion

Invasion is a simultaneous 2-player arcade game for the TRS-80 CoCo.

Each player controls a small ship at the bottom of the screen that moves laterally and fires directly forwards. A number of enemies cycle in front of the players, and fire towards the bottom of the screen. Numerous shields offer protection, and the players must fire between these shields to destroy enemies. If a player takes 3 hits, it's game over for that player. The L and R by the scores at the top of the screen indicated the left and right player; this indicates both which joystick port and which side of the playfield the player starts at.
