Tux Invasion is an arcade game developed by stepmat for Android devices. It is a free game that includes five levels of invasion in campaign mode, each with 20 full waves of enemies. The player must place turrets at the start of each wave and then move their character around the map trying to avoid the enemies.

One of the best features of Tux Invasion is that it supports both tilt and touch modes of control. This makes it accessible to a wide range of players with different preferences. Additionally, the game includes bonus flappy and two-player tennis style mini-games that add variety and fun to the gameplay.

Another great aspect of Tux Invasion is that it is free from adverts and hidden costs. This is a refreshing change from many similar games that bombard players with ads and in-app purchases.

The programming by Matthew Stephenson and music by Richard Gottlieb complement each other perfectly, making for a seamless and enjoyable gaming experience. Overall, Tux Invasion is a challenging and entertaining arcade game that is definitely worth checking out.
