Warframe [official site] already looks like a game about sealife thank to its exotic power armour designs – with hammerhead helmets, lobster armour, unspeakable many-eyed horrors from the depths, and pearly nacre coating everything. Actual underwater combat was inevitable, I suppose, or all those watery warframes would get crabby. Crabby. Like a crab. That’s a joke.
The latest expansion, Echoes of the Sentient, has added underwater action in new levels and, for land-lubbers, new parkour moves. It’s all out in the free-to-play co-op shooty dungeon crawler now.
