Chicken Invaders 4 Ester Linux is a video game featuring battle between the user and chickens from outer space. User can fire lasers from the cockpit of a spaceship or other weapons positions.

Wave after wave of the Chicken Invaders attacks and the user is to make good with each strategy and weapon on their disposal.

There are strategy approaches to this game that call for itemizing one's tools and weapons.  Keeping alert to one's toolbars for life and weapons and then planning ahead for more challenges from the AI.

Each step in the game gathers info on the user and presents both basic and unique offenses and defenses so no two games are alike.  The sound effects, graphics and more are professional enough to give the user a sense of escapism into a different world where chickens from outer space attack.
