Killing Floor vs S.T.A.L.K.E.R.: Clear Sky
Killing Floor
Killing Floor is an intense survival horror first-person shooter game that is set in the post-apocalyptic and devastatingly ruined country of England where a series of military-sanctioned cloning experiments had gone awry. Play with up to 6 of your friends cooperatively as you attempt to survive for long enough to clear the area you are airdropped into of any zombies or you can simply play solo. Unlike most similar games, Killing Floor has a non-linear gameplay where you can actually weld doors shut to redirect waves of zombies. The gameplay is also more tactically sound rather than the bullet-hell stuff you'd experience in some of the more arcade-like shooters.In addition to having an arsenal of weapons for you to choose from, the game also features a persistent perks system which lets you to convert your in-game achievements into permanent improvements for your character's skills and abilities. The game even has mod support, so you can create new levels and mods for the game and share them with the world.
Killing Floor may be a rather old game, but it's still as fun as it was before. The cooperative gameplay guarantees hours of fun (as well as yelling and perhaps cussing) for both you and your friends as you try to stem the tide of zombies rushing towards you.
S.T.A.L.K.E.R.: Clear Sky
S.T.A.L.K.E.R.: Clear Sky is the second installment in the S.T.A.L.K.E.R. series and yet is the prequel to the original game. In this game, a group of stalkers have unwittingly triggered an explosion of anomalies when they ventured into the heart of the exclusion zone - the Chernobyl Nuclear Power Plant itself, turning the entire zone into an unstable mess that continues to quake with anomaly outbursts. Stalker factions have also erupted, further adding to the overall chaos of the region.S.T.A.L.K.E.R.: Clear Sky is essentially similar to the previous game, though it does have some significant improvements. For instance, the game is a lot more stable, which is ironic considering that all the storyline in this game talks about is how unstable the zone is. The weapons and armor in the game work better than in the original since they can, finally, be repaired. Artifacts are harder to find here but is a lot more rewarding and well, generally the overall setting feel a lot more realistic.
This is definitely a nicer game to play than its first game, but it's not really comparable to the third game of course. However, if you love the S.T.A.L.K.E.R., you might still want to consider buying all three games via its Steam bundle.
