Gameplay is mainly centred on exploring the radioactive post-apocalyptic “Zone” of Pripyat while surviving. There are a lot of weapons, ranging from knives to grenade launchers. The guns can be deeply customised with different scopes, suppressors, and magazines. There is a wide selection of body armour as well. You can undertake difficult but very rewarding quests, and as you complete more and more of them, your influence will raise and you will get unique jobs which have great story elements. The gunplay is realistic and accuracy demanding, and it’s mostly better to leave unprovoked foes alone so you can save ammo and keep your weapon from wear and tear. There are dangerous and terrifying enemies everywhere in the zone, and there are anomalies. I won’t spoil anything about them though.
Graphics is quite good for an indie game. The atmospheric, dark lighting really suits the post-apocalyptic feel. You can play it on a laptop or a low-end PC, as it doesn’t demand a high-performance system.
So, I hope you guys will give this wonderful game a try. And if you like it, post a review on the site because the developers deserve it!
