Striker

Striker is an arcade-style helicopter shooting game, with CGA graphics and five missions to complete. It's somewhat similar in style to the arcade game Scramble. This game gives you both bullets and bombs to destroy obstacles, as you fly through several similar-looking missions to pick up spies, drop them off, etc. You'll need to carefully land your helicopter at the end of the level, but thankfully it's pretty easy. The game plays well enough and is quite simple. You can reconfigure the keys by pressing "O" at the title screen, then pressing "K" to adjust keyboard settings.
