Wildcard power weapons?
If I had one that had me more worried that the rest, it would be the power weapons. That said, as long as map based weapons are still existent, and the weapons that spawn "randomly" aren't entirely random but rather where they spawn varies then I'm happy.
I can handle custom starting weapons, in fact I wanted it. Sort of. As long as we can't spawn with guns like snipers and shotguns then I am happy. If I were to take a guess, we will choose between weapons like the AR, BR, DMR, Carbine, etc. If they will be customizable I am not sure, it may be possible to do certain cosmetic upgrades.. maybe custom scopes, but I don't think it will go beyond that. Basically, it seems it will be Halos take on a system like Gears of War 3 mixed with Black Ops. In other words, I'm not too worried, I think it will be fine. If more details hit that aren't so positive, such as starting with snipers whenever you want, I will join the freak out list. For now, consider me intrigued and excited.
Also, I fully expect Barebones/Classic options to be built into the MP.
Yup, I fully expect a mode like this, maybe more basic than Reach's FF, but still a spiritual FF successor.
Yeah, imagine if there's a Spartan Ops game type called Siege. That's Firefight, right there.
