Scary as Hell! However it has ALOT of bugs and faults that just disappoint you after waiting this long for the game...
There are some downpoints however you can't sell your stuff to vendors for cash and anwyays if you could cash seems not needed seeing as you loot everything. The side quests are also pointless and just not fun, theyll often poune themselves on you without you knowing and you'll end up killing someone needed and that bugs the quest and it's stuck in your tas list for ever with waypoints being annoying.
There're too many bugs in this game that just make it unfun afterawhile however the atmosphere and style of the game + how scary it is and the amazing setting just makes up for it for me. The main story is also not very good and you can often get lost and just overall it's just not good lol. Theres nothing "epic" that happens and just feels more like a link quest on a MMORPG. However you do see amazing sights and scary places and whent he main story finishes you just feel like you want MORE and t have a HL like story but in Chernobyl.
The loss of vehicles also has a bad impact on me and i'd love to drive about, i'm sure a modder will put them in but it's a shame not having them in the main game from release.
The Multiplayer is just crap lagy and buggy and the hitboxes are all voer the place, its unoptimized and poor don't buy it for multiplayer.
Th Graphics are just AMAZINGLY detailed IMO and great art style and captures it perfectly. They are getting dated but the detail just hides that and it's the best looking FPS soo far + sooo scary and amazing lighting. The weather effects/cycle and day and nigth cycle is also great.
The sounds are great too and so is the music, i can't really fault it.
Overall it's a fantastic game but has faults that after this long in development you don't expect in a game which are a let down. The guns to fire just feel amazing and havn't been impressed by guns in a game this much since CS.
