played for 18~ish hours, and spent around 3 of those searching for a server where three slots were open for our group or waiting for someone to DC. The aiming and doing damage feels very unresponsive if you've played other games. One of the endgame locations is the bunker, and it has a few glitched spots. Plus the AI respawn even if you've killed them all and haven't left the area.
It's fun to snipe people or gun them down with shotguns, but the prices at the traders are very unbalanced. If you're going to play it, don't pick the looter faction, as it has less content / quests.
Vehicles are also buggy, the physics are weird, and things you store in the trunk disappear if the area is unloaded - so you can't loot the bunker easily that way. The APC is overpowered but also glitched. The AI is dumb, as if you're outside of their range, they won't react to you sniping their fellow soldiers. The AI doesn't work well with more than one person, as it'll target that person until they die, and will ignore the others even if it's being shot by the other players.
It only has around 10hours of content if you're playing alone and going for getting done with the civilian quests and gathering supplies to raid the bunker.
Pro-tip, don't try to fight the 8 AI who are stationed outside of one of the "Main" bunker entrance, as it's easier to just take one of the 3 other alternative routes.
Once you have a sniper like the SVD, you can cheese AI pretty well, or if you use an RPK they won't be able to fire off a single shot before you've headshot them atleast 3 times.
Vehicles also don't lock, so you have to take ALL of the parts out or else someone might steal your car and parts, plus, even that is risky as they can just sit in the driver seat forever.
EDIT: So i'm already bored unless they fix the server browser and the looter quest line.
