They consider you a traitor and will kill Kane's family if he doesn't comply
There's only one multiplayer mode in Kane & Lynch, and it's a great idea. Unfortunately, the idea doesn't translate into a great or long-lasting experience. It's called Fragile Alliance and puts up to eight players in one team of criminals. Then, it sets the team off to steal money, cocaine, and jewels from various locations seen in the single-player game. So you might start out in front of a bank, run in, collect a bunch of cash, and then escape from in a van out back. The catch is the way the money is split up among teammates. If you all work together, the money is split evenly. But at any point, a player can go rogue and gun down one of his teammates. This brands you a traitor; thus, any money you collect and escape with is yours to keep. Of course, this also means that other players who are still part of the team will try to waste you before you escape with their hard-stolen loot.
The core gameplay in Kane & Lynch is your standard third-person shooter with cover elements and a light dusting of squad tactics. You can fire from the hip, but it's somewhat more accurate to fire while aiming. Unfortunately, even when you're aiming, hitting your targets is more difficult than it should be because your automatic fire has a wide spread on it. Kane is supposedly a badass arch-criminal; he should be able to hit his targets with short, controlled bursts. You're able to get behind cover and either blindfire or pop out for aimed shots, but there's no easy way to stick to walls. You don't press a button or anything; instead you sort of get up against a wall and turn sideways. Then after jiggling the controls back and forth a bit, you'll eventually snap into place to get behind cover. It's such a pain that you'll rarely want to use it, and it seems like you're always snapping into cover behind something at the most inopportune times, making the game quite frustrating. There's no health meter, but if you go down, you don't die immediately either. You can be revived by one of your teammates with an adrenaline shot. If you get that shot too frequently, you'll overdose and die.
