This far-out, space-shooter game replaces the usual mutants or aliens with squawking chickens who want to take over the universe. The concept reminds us of programs such as Space Invaders, since you must blast your way through hordes of chickens in Santa suits while avoiding their fire. The holiday theme also is reflected in the soundtrack and the graphics, with snow falling across the outer-space scene. We rather liked the graphics and the sound effects, and we appreciated the ability to reconfigure the control keys to our liking. You can't disable the audio, but you can choose from two difficulty levels and play with a friend. Though Chicken Invaders 2 Christmas Edition is quite entertaining, some users may find gameplay too repetitive, as many of the worlds are very similar with the exception of the chickens' appearance. Still, folks who are fond of arcade-shooter games may find this program enjoyable, especially around the holidays.
