Wild idea, but I was recently think about what a mod for Halo: Spartan Assault and/or Strike would look like if you turned the game from a simple isometric shooter into an action roleplaying hack and slash similar to Diablo for example. Might be interesting? I would play it, and maybe they could recycle a lot of the work they did with those games.
Would need to be its own game spin off and probably series. I could see it being done eventually though, perhaps by playing an arbiter or a chieftan or something known for its CQB and melee prowess
Yeah, I know there have been some wild attempts at Halo spin-offs including Halo Titan, the cancelled WoW-like MMO (which we may see very subtle traces of in Infinite), but as the hacknslash genre grows, it's probably the best way to do a third person top-down game, short of just an RTS. Or I suppose they could try to make a turn-based tactics game ala Gears Tactics - That would be interesting lol.
