In Pereptuum you can drive the combat bots and mech of three different factions.
Factions Part 1. - Pelistal Faction (Missiles)
Factions Part 2. - Thelodica Faction (Lazers)
Factions Part 3. - Nuimqol Faction (Magnetic slugs)
The combat system built around the factions is based on a rock-paper-scissors damage mechanic. Each faction has a high resist and a damage type they shoot that corresponds with damage resists.
Easy way to show this system is with a chart.
