I've been playing DayZ a bit. It's incredible for its ability to conjure up set-piece moments of intense action, terror, communication out of absolutely nothing.
I play with a friend - best moment was when it was pitch black, about 2am in-game time, no moon, raining and thundering; couldn't see a thing. We proned our way towards Balota control tower hoping to swap our Lee Enfield/Winchester combos for something a bit more weighty. Had to use our ears only for navigating in-between the roaming zombies - really intense stuff. Finally got into the control tower and went up top. Looking towards the windows inside noticed a weird bump in the silhouette of one, but assumed it was a chair or something. Then moments later, there's a flash of lightning and the room momentarily lights up - it's not a chair, its another fucking survivor - we'd creeped into the tower just after him and neither him or us could hear the other person's footsteps over the noise of the rain. Everyone starts mashing the fire button, and he goes down, my mate gets hit and just about survives. Then the dead guy's mate comes up the ladder on the side of the building while we're bandaging and kills both of us!
Also had a 30 minute firefight north of Stary Sobor that was amazing. 2 vs 3, in opposite treelines - no-one had a sniper rifle, we had I think an AK & and an M4, they had an AKM, and something similar for the other two. Their spare third guy kept trying to flank us, and we kept pinning him down, but eventually we ran out of ammo and had to leg it north.
I also like to try to spook people at night. Sometimes I follow people, just out of any flare-light, and then when the oportunity arises I either throw flares, smoke grenades, M67 frags, etc around them, but without identifying myself. Some people go crazy over direct when you do it lol. One guy took up his Makarov and pumped about 20 bullets into the darkness in the opposite direction.
