Drive your tank and defend your planet from the invasion of aliens who want to destroy your city.
Aliens come in hordes from space but you will watch and destroy as many as possible before they destroy your city and conquer your planet. Always be on the lookout, scan the sky and, if possible, catch aid as well, because aliens are numerous.
Google Cardboard required. To move forward slightly lower your head, instead rotate it to aim wherever you want and if you meet an enemy the automatic fire cannon will do the rest! One last warning, always look around and don't stay still, sometimes running away is better!
