they made a weird free-to-play live-service single player PVE game called hawken: reborn, it's pretty crap and i say this as a pilot-brained mecha-maxxer. i think they did eventually add a limited like 4 player co-op PVE mode but it launched with singleplayer only. confusing and disappointing really and theres been no new updates on steam in months.
at least you can still play original HAWKEN on xbox, but not pc or playstation for some reason. they added a botmatch mode to deal with small playerbase so thats cool.
