This is the Multiplayer portion of The Ship. I said I didn't like the singleplayer, but the multiplayer is a totally different story.
Also another little note, at time of writing, the in-game server browser is broken. You can find games through Steam (Steam Window: View > Servers > Change Filters > set game to The Ship).
The Ship seems to be a lesser known, yet highly underrated game about murdering other people without being spotted. It's a true blue stealth game in that you actually have to kill your quarry without being seen by anyone. If you pull out a weapon in front of a guard, security camera, or are seen holding one for too long by other players, you get arrested and penalized. The game also punishes random deathmatching, so players have less incentive to grief. The game is really tense because everyone is a target.
while you're hunting your target, someone else is hunting you, and you have no idea who it is until they start looking shifty, make a move on you, or kill you.
It also combines a little bit of The Sims in that you have to manage your needs: hunger, thirst, toilet, cleanliness, boredom, fatigue, socialization... All the while trying to hunt down your quarry. The game also encourages mixing up your murder weapons by increasing the money you get for a kill with a given weapon the longer it goes without being used. Once a weapon is used, it drops to the bottom of the list and only gives you the minimum payout.
The game is a buttload of fun and deserves more love and attention. This game also comes with a bunch of copies that you can give to friends. I highly recommend it, especially if you can pick it up during a sale.
