I take it this game won't have a Friendly Fire option? I can imagine a lot of complaining over dumbasses using Martyrdom if it does.
lol no. but you can get killed by your own grenades, airstrikes, RPG's, etc.
I'm at about level 20. The M60E4 light machine gun seriously kicks ass once you get used to it. I also got the slight of hand perk so it relaods in like 2 seconds. Slight of hand also affects how fast you reload your RPG which makes it look kind of freaky. I've only unlocked a couple perks (martyrdom and slight of hand) and the light machine gun but it looks like the next 5 levels will have the cooler upgrades. Except for the G3 assault rifle. I picked up one of those off the ground and it's single-fire only, doesn't look like it's good.
