Battle Area is a top-down tank shooter in the tradition of the 1980s arcade tank games: you drive a tank around a walled arena, shooting enemy tanks while protecting your own base from them.
Walls can be destroyed to open new routes, which turns the map into something you reshape as you fight. Losing your base ends the game regardless of how many enemies you've killed.
Keep the walls around it intact and position yourself on the approach the enemy is using. Chasing tanks around the map is how bases get destroyed.
Yes — most walls are destructible, which lets you open new firing lines but also lets the enemy reach your base more easily.
Yes — a light 2D game with nothing to install.
