Another fantastic looking retro game from Puppygames! It is the 2014 version of the classic game, Space Invaders, where you are the last surviving tank commander defending Earth from alien invasion.
The idea is still same as in 1978. Alien forces slowly approach you, while you bring destruction with your tank and laugh at them. At the same time you collect points and upgrades, which you then use for tank upgrades between levels. Upgrades vary from shields to extra ammo and smart bombs etc. Nothing major or too complex though, just enough to give the old concept a refreshing twist.
It's a great and challenging mini game that pretty much anyone with two working hands and a set of brains can start playing immediately.
