If Halo and Farcry 5 had a ginormous crossover, there should be alot of stuff thats cool and amazing. Heres my list that should be in the game if it happened.
Master Chief, Arbiter, and Sgt Johnson as specialist guns-for-hire. - Halo outfits including a Rookie outfit, create a spartan, and Jorge, literally JORGE. - Guns including the Assault Rifle, Battle Rifle, SMG, Silenced SMG, Magnum, Gauss pistol, Sniper Rifle, SPNKR, some sort of LMG, and Covenant weapons. - Vehicles such as the Warthog(Turret, Gauss Turret, Transport, and Civilian), Mongoose, Falcon, Ghost, Shadow, Banshee, Scorpion, Wraith, Phantom, and Pelican.
in infinite side missions are confirmed, and the game is semi open world but divided into stages. its also been confirmed that stages can be revisited during the same playthrough. seems like the game is going to be something more like borderlands x halo. slim chance but I’d love to see weapon and utility upgrades.
