Arkheron's an interesting game (I'm about to throw a lot of adjectives at you, don't get scared): an isometric PvPvE battle royale-type action RPG where you and two other mates try to ascend a tower in the afterlife.
Rounds play out as you and your fellow echoes ascend a tower, having showdowns at the end of each floor where you take on another team before moving on. In the interim, you run around fighting monsters, picking up loot, and fine-tuning your build before you go onto the next bout.
