To be perfectly honest I'd be happy if sniper rifles were never added to the standalone. Too many bad memories of being one-shotted while running through a pitch-black forest in the middle of the night because some chucklefuck had turned their gamma all the way up.
They have two snipers (well, one and a half) and just about every gun is a one- or two shot kill.
Maps, food and some clothing spawns in cars. Sedans spawn the most, vans may not spawn anything. You can even find half maps in the cars.
Has anyone seen a city map yet?
No city maps. Thusfar I've found maps of the NE, E, and W. No clothing and very little food in cars, more often canisters of gas. I found some rifle rounds in the trunk of a police car.
I think you missed the point about the snipers (as an aside, to my knowledge the only one in the standalone is the Mosin, and that has a relatively low-zoom scope). One of the least-fun aspects of DayZ is that pretty much every gunfight either consisted of one party sniping a defenseless person from 500+m away, or two parties with high-powered scoped longrifles waiting to see which one would get impatient and poke their head out first.
That kills the interesting parts of combat; nobody would ever willingly choose a carbine, shotgun, or assault rifle over a longrifle. Even without things like the AS-50 and thermal scopes, sniper rifles (especially the DMR, at least in the hands of someone who understands how mildots work) were obscenely good. The standalone is seeing a lot more of the intense MOUT-style confrontations, because there's only one sniper and it isn't even the best weapon in the game. Engagements are trending more towards the ~50-150m range with a sizeable chunk of CQC, as opposed to "Whoever has their viewdistance set further out wins".
Every gun is a one-shot kill with a headshot, but non-longrifles can actually take anywhere from 3-4 shots for most ARs and carbines to upwards of 12 shots for SMGs and some pistols to do enough blood damage for a kill. There's also the point that non-longrifles are much more difficult to get headshots with at long range, and you don't have the guaranteed 2-shot kill if you miss. I've seen both ingame and on recorded footage people not dropping until they've taken a good chunk of a STANAG magazine.
