Krazy Alienz is a unique take on Space Invaders, which is designed to capture the feel of the original game, but also offer some modern twists which enhance the gameplay rather turn it into a mindless button bashing session.
Smooth 60 fps action
Full local multi-player support (1 to 4 players)
In-game bonus levels (earn some extra points and therefore lives)
Three Games in one: Normal, Skill-Shot and UFO Blaster
In-game stats: Compare how you are doing against other players as the game progresses (or skip it if you’re not fussed)
Local highscores for all three game types – Networked Highscores are slated for a future patch free of charge.
Lots of options, from re-sizing the gameplay screen to fit your TV, to turning powerups/downs off for the classic game feel
Custom Soundtrack support – just start playing your own music and the game music will turn off automatically
Unlimited number of levels – go all out for the highest score!
