Chromium - Arcade (Space Fight) Linux GameFollow @ggarron
This is the first game I installed some months ago in my Ubuntu PC
It is an old-fashion game 2D, for all of you who started with Atari, like me :).
What you have to do is to fight against space ships, (lots of them) and avoid them to pass the bottom limit of the screen, if that happens you lost a fighter.
You can get the skulls for weapons and the penguins for more fighters and energy.
To have it installed just enter:
apt-get install chromium
