Hi,
What if 343 Industries developed a new Infection game mode ? That would be full of the adrenaline kit or races of hearts. The absolute nightmare. I would introduce a couple of ideas like:
Outbreak: One of the 4 opponent teams tries to pick up a secret UNCS package. And as soon as the annihilation starts. The plague is waiting.
Anyone who has been infected naturally starts as an infector.
Infection Ultimate: My Favorite. 50 Spartans are abandoned by an UNSC-AIRSHIP. The ship is being mastered by an intruder. The Spartans discover Floods on the planet and in the crashed ship. Your decision is in your hands. In the Open world you can go in groups or alone. Whatever, may the best survivor win.
As far as I can see the fair will be abandoned bases in this cemetery with guns and ammunition. Even vehicles, but a few rusty and old. But one of them would be the flamethrower with the shark grin, the other the fire grenade. Who, but needs more dangerous weapons, has to enter the diabolical airship. That means there will also be mutants in this Open world game. They can get you with their noose. Infected Spartans are accompanied by real Floods. There should also be a lot of commendations, medals of honor and credits. Strategic paths will be infinite.
Mutant Eblem: If 3 Spartans catch 5 first without dying. Mutate and be able to do things that others cannot. Like crawling on walls, dragging Spartans with their noose and their health is enormous. Are hard to turn off. Alpha zombies are a bit difficult, but mutants will give you hell. Mutants can cause a survivor to mutate through their spores. The animation here are not for little princesses, that means it will be brutal here. Not too brutal, but brutal.
I look forward to your answer if you want to try something new. Also, I would ask 343 Industries if that idea is nice. Perform this mode once a week. With lots of praise and credits. Plus, this would be horror fun for newbies.
