Arstechnica have posted their review on the Aliens VS Predator demo which came available last week.

Here are the review:

Aliens vs Predator may very well be a good game, but the demo doesn't do much to sell it.

The demo is multiplayer-only and only showcases one map and one game mode: deathmatch. The servers are public and trying to find a game is an exercise in frustration. In over two hours spent with the PlayStation 3 version of the demo (it's also available on the 360 and PC) I managed to play a scant three games. And one of those got disconnected. Ben had similar issues when trying to connect to the PC version.

Once you actually get in a game things run pretty smoothly, though deathmatch isn't really the best way to show off a game with three unique races to play as. Especially when you seem to be randomly assigned a race. After a brief loading screen displaying the controls for the game, you're tossed into the fray with no other guidance.

This is fine when you play as the marine, who controls much like you'd expect in a first-person shooter. He's slow, and wandering dark corridors filled with aliens scampering up the walls and semi-transparent predators running around can be intimidating. But you do have a gun. The marine seems to have the most firepower at his disposal, which is of course upgradeable via new weapons scattered throughout the level. But his slow movement also means that it's easy for a clever alien to sneak in for the kill. He's clearly the "all-around" character to play as: not too exciting but definitely familiar.

Playing as an alien, meanwhile, takes some getting used to. You may not have a space rifle in your claws, but you are much more mobile. You can climb up walls and run across ceilings, something that's pretty disorienting at first, which isn't helped by the sometimes-awkward transitions from one surface to another. Once you get acclimated to the way the alien moves though, it becomes clear that their mobility makes up for the lack of weaponry. You can stay hidden and set up traps, attacking foes below you with your powerful tail. And since the alien is both very fast and low to the ground, it's pretty easy to get yourself out of sticky situations.
