Since early 90's tanks and mostly tank games are extremely popular. I hope everybody remembers Tanks 1990 game where your mission was to defence your base and destroy the enemy.
At Tank Trouble some of missions stays the same but main difference is that you don't have any base, so you don't need to defence anything, the only mission is to destroy the enemy tank.
Tank 1990 was two-player game and tank trouble has up to three-player modes.
