Tank Rectangle

Tank Rectangle is a simple, retro tank shooting game. You move, aim and shoot, with survival as your only objective. It currently has one map and no boss or plot.

Cards and upgrades

At the start menu, you equip one ability card. Each time you level up, you choose one of four random cards to improve an attribute or ability. You can also power up abilities by collecting multiple copies of their cards. Once you have collected more than one ability card, you can press E.

Enemies gain levels as time passes, with their attribute upgrades chosen at random. You can choose your upgrades to suit the direction of their development. Enemies can explode when you get close.

Sound and surroundings

The game has an environment system that makes sound important at night: you need to judge enemy positions by listening.
