Vindicators

Vindicators was produced by Atari Games in 1988.

Use your tank to destroy other tanks, turrets, and saucers while collecting fuel, stars, and bonuses along the way. Exit the level by finding the key that unlocks the doors. Use collected stars to customize your tank with speed, power, shields, smart shots, and bombs.

Once a game has been started, the 1P/2P buttons allow each player to rotate through any special weapons they might have. At the end of the 15th level, you must destroy a huge monster with many eyes.
