BRIKWARS is the plastic-brick tabletop wargame that throws the peaceful worlds of construction toys into wanton chaos and destruction!

Bring and build your own armies, vehicles, and monsters in an all-out war for construction toy glory, with a robust system to incorporate whatever you create. If you can build it, you can bring it to battle in BRIKWARS!
The Kassarian fleet prepares for battle.

Gladius posts to the forum with a full-fledged ruleset for microscale Lego spaceship combat, and cool microscale Lego spaceship photos to back it up.
