Polyversal

Polyversal is a science-fiction mass-combat miniatures game. The game is for two or more players and is set in a plausible near-future Earth, but also lets you create a setting with its open-source approach. Polyversal is compatible with all 6mm-15mm miniatures and is fully customizable. Boxed sets of the game feature miniatures from multiple 6mm and 10mm miniatures manufacturers including Brigade Models, Dark Realm, Plasmablast Games, Microworld Games, and Hawk Wargames (10mm walkers).

Polyversal also allows players to design their own Combatant Tiles, which contain all stats for units in the game as they see fit within the Design Rules. A points-based system balances everything out based on the selected options, weaponry, armor, class of unit, etc.

Multiple videos help explain Polyversal's gameplay, Command and Control, and Storyline. Collins Epic Wargames also provides a free highly-condensed print-and-play version where you can get a feel for the game with a limited portion of the rules.
