Rampart
Rampart is an arcade game, first released in 1990 by Atari Games, that combines the shoot ‘em up and puzzle genres. Players build their castle from Tetris-style pieces, place cannons, bombard the enemy, try to repair, do it all over again. This cycle continues until either the player fails a repair round, or enough ships in the enemy’s fleet are sunk. When the opposing navy has been depleted, the level is won, and the player may then choose another level.
