Exoprimal looks cooler in every trailer I see for it. It's pretty fun too—those exosuits might remind you of Bioware's failed Anthem RPG, but Exoprimal's armaments are purpose-built for slaughtering dinosaurs that drop out of sky portals. Each suit is essentially its own class, including tanks, supports, and damage dealers.
The main mode, Dino Survival, is a hybrid of PvE and PvP against two teams. I was having a great time bisecting raptors by the dozens in the closed beta a few months back, but the match would also lose steam in the final phase when the teams appear in the same arena to fight it out PvP-style.
