Chicken Invaders 4: Ultimate Omelette adds a thanksgiving twist to the shoot 'em up series inspired by retro arcade video game Space Invaders.

Turkeys revolt

Ignoring the fact that Thanksgiving is actually about turkey and not chicken, Chicken Invaders 4's storyline is full of fun. The chickens (not turkeys) have staged a revolution against being eaten every holiday season so you must put them back in their place (on the table ready to be eaten). This storyline is revealed in a slightly lengthy, Star Wars style scrolling text introduction.

If this is your first foray into the birdy saga, you'll find it's quick and easy to pick up. But if you've played all the previous versions, Chicken Invaders 4 may seem slightly lacking in innovation, new features, and different backdrops.

Stick 'em up

For fans of the birdy series, Chicken Invaders 4: Ultimate Omelette will seem pretty familiar. Continuing on with the poultry-themed vertical shoot 'em up gameplay, killing the chickens is again the ultimate aim of the game. To make this easier, you can collect power ups along the way which upgrade your laser, meaning you can destroy the waves of chicken that come your way quicker and easier. Collecting keys unlocks even better weaponry upgrades.

The waves of chickens come in tons of different formations, keeping you on your toes the whole way through. These waves culminate in a big boss, which isn't as tricky to defeat as you might expect.

Good, silly fun

What Chicken Invaders 4 lacks in originality, it makes up for in silly fun. It's easy enough for casual gamers, but with plenty to offer arcade fans. Not the best game you'll ever play, but good for passing the time.
