The 2010 Aliens Vs Predator is actually pretty good. Don't get me wrong, its not high art. The characters suck, and the story is the bare minimum you would expect out of the franchises.Lance Henrikssen does gives a good performance as Karl Bishop Weyland; he's pretty much the only notable character in the game but his presence really elevates things. The collectable pickups do nothing, the audio diaries are uninteresting, and the gameplay is a little squishy. But once you look past that its a perfectly serviceable game. All of the weapons handle pretty well, and interestingly enough the game tends more towards fewer, overpowered weapons rather than giving you bog standard starter guns.
For instance, the Alien claws can rip apart just about anything in a few swipes, even on hard difficulty. The Predator's weapons are hilariously overpowered, but are limited by a painfully small pool of energy pickups. The Marine has a pretty good pistol, a shotgun that can one-shot xenos if they get in close, and the standard Pulse Rifle can shred just about anything and holds 99 rounds just like in the movies. There's no SMGs or anything, and ammo is very abundant. It makes the game easy, but its consistent with the technology you'd expect to see in a futuristic setting and the stuff detailed in the Colonial Marines Technical Manual.
I can see why fans of the original hate it, but if you're not as familiar with the oldschool one and you're a fan of Aliens you'll probably enjoy the 2010 game. I haven't played the PS2 one or Extinction though so I'm not sure how it holds up against more modern AVP games. I can also see why people were so dismayed with it back when it was still $60, but its now well over 14 years old, pick it up in a sale or something. Compared to Aliens: Colonial Marines its a god damn masterpiece too. It felt like Rebellion actually gave a shit and wanted to deliver a serviceable product even if it is kind of underwhelming.
