S.T.A.L.K.E.R.: Clear Sky vs Urban Dead
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.
Urban Dead
Urban Dead is a mainly text-based MMO game set in a post-apocalyptic city that you can play straight from your browser. Assume the role as an urban survivor trapped in a quarantined city just trying to get by. However, unlike most games, Urban Dead is an MMO and as such, you'll encounter other players as you wander from place to place hoping to scavenge something - anything - that might help you. These players can be friendly or hostile (though, it's more often the case the latter).You can even set up a center of operations, so to speak, by clearing a place out and lock the place down. Other players might try to break into your base though, so it might be best to recruit a few trustworthy players to help you maintain your base and keep it as well as everything you hoard in it safe from any looters. Of course, there are also zombies that will attack your base and you, if you are unlucky enough to bump into one or an entire horde.
Urban Dead is a quite different text-based game admittedly, but it is still very addictive to play. It might be best to play with friends though due to how its base building feature is structured and well, there is always safety in numbers.
