chormium-bsu(6) is a fun and hard top down shooter game. Try it out from
the ports. By default the controls are arrow keys and space.
At least try out the first level for 5 miinutes. Spoiler ahead.
You have been warned.
It's hard, right? If you use a laptop touchpad for movement, you will be
able to accelerate and stop almost instantly. This isn't even the best
part. Try shooting while moving. Your machine gun fire rate will be
crazy fast. The ammo for additional machine guns (yellow skull) will be
used up as fast as if not faster than plasma guns (purple skull).
