It is a shame that killing off hordes of enemies in Exoprimal is so boring because the idea of a horde/hero shooter blend sounds fun and the game controls, looks and is optimized excellently.
Maybe if they had focused in the horde aspects instead of having to split their attention with the fairly generic PvP mode it wouldn't get repetitive so quick, but as it is the lack of enemy and map diversity, the lackluster layouts of those maps and the relative ease with which you dispatch enemies was enough to make me uninstall the game in just a couple hours.
The soundtrack was pretty nice too.
