Arenum is a free fantasy gladiator team management game. What this basically means is that you control a team of gladiators, or as they are called in-game, Sentinels. You hire randomly generated gladiators from 30 different races with their own unique abilities and traits and build your dream team. When the team is set, you'll face other teams and fight against them in tactical turn-based combat.
