I tried it some days ago and really like it. You normally find enough games to join in the evening, so you don't need to bring your own 3 friends every time. Rounds are also pretty short so you can quickly play a few times between other things. In case you do play with people you know, better use TS it helps a lot. Ingame voice chat is also possible, but rarely used and seems to have a poor quality. So if you enjoy slaugthering all kinds of alien beasts for no deeper reason using tons of diferent equipment in a nice environment and get a bit tactical with friends - Alien Swarm is your game.
