Rampart is a pretty cool arcade game that mixes shooting action with block-style puzzle gameplay. You control castles on the land, and you place cannons around those castles to fend off hordes of incoming ships. At the same time, the ships are shooting holes in the walls around your castle. But battle only lasts for a few seconds, and then a rebuilding round starts, where you have a limited amount of time to quickly patch the holes in your walls before battle begins all over again. If you can't surround at least one castle with walls, the game ends. It was an interesting mix of action back in its day, and it's still interesting today. Unfortunately, even the three-player online play can't make up for the PlayStation 3 version's terrible, touchy control.
