In the tradition of the B-movie comes Dark Sector, a B-game if there ever was one. There are plenty of, ah, "quirks" to go around, and it's unlikely to be the kind of game that gets Game of the Year consideration from professional reviewers, but most players are going to have a good time.
You star as... some guy, doing... things, for... some... purpose? Okay, I didn't pay much attention to the rather generic cutscenes. From what I gather, an alien infection struck the earth several decades ago. It turns humans into mutated zombies and worse. You're a government agent dedicated to eradicating the virus and its victims, with extreme prejudice if necessary.
Early on, you're infected and begin mutating into something rather alien. The most obvious change is your right arm, which turns into this weird lumpy husk that can produce a throwing weapon called a glaive. It acts like a boomerang, returning to your hand after each toss. It's a surprisingly effective weapon, especially in combination with a Burnout 3-ish aftertouch system that allows you to slow down time and direct the weapon around corners, through holes, and ultimately directly into whatever part of your enemy suits your fancy.
You also have more traditional guns at your disposal, including pistols, shotguns and rifles (among others). Both these and the glaive can be fired either from the hip or from a Resident Evil 4-style aiming system that ensures you can't really move and aim at the same time. It makes one wish more designers would adopt this system, as the controls work just as well as it did in that legendary game.
You'll start out battling humans, then rather less-human enemies get mixed in. The former are much more enjoyable as enemies, as gory slicing-off of limbs and bloody finishers never gets old. Eventually you'll discover ways to charge up your weapon for extra damage, effects, or greater damage radius.
The graphics are surprisingly good, showing that the artists were kept busy during this one's long, long development cycle (it was originally intended as a PS3 launch title, I believe). While the palette is often the dreary muted grey/brown one seen in games like Gears of War, there's good detail all around. Enemy animations are generally excellent.
The worst thing one can say about this game is that the bosses are horrible. Annoying as hell, with plenty of cheap one-shot deaths and you-can-shoot-me-only-in-this-one-specific-place-with-this-one-specific-weapon-only-after-doing-something-else bullshit. Did I mention that the feedback is either poor or nonexistent, so you'll just have to guess to see if you're doing the 'right' attack in the 'right' place? Wash rinse repeat several times within each fight. Ugh.
Is this fun for ANYONE? How does this kind of stupid garbage make it through the testing process? Is there a evil tester somewhere who cackles with delight after each game he sabotages by insisting that these fights will be greeted with open arms by players?
There are also some glitches here and there. The attacks occasionally don't charge correctly, and actions sometimes don't work as intended even when the correct controls are used. Enemies corpses are prone to the St. Vitus' dance that was often seen in 1st generation 360 games. The weapons upgrade system is poorly implemented, making it hard to determine what the effect of upgrading your weapons will be and which weapons are better than others.
Even with those annoyances, I really enjoyed the game. It takes a lot to get me to stick with a game even through annoying boss battles, and the lure of additional opportunities to guide my glaive through Bad Guys' heads was more than enough. The first 3/4 of the game is almost solid fun, making it well worth picking up as a rental or on the cheap.
* Okay, I didn't technically finish it, but I got to the last boss and decided that
my life wouldn't be markedly improved by banging my head against the wall for the next two hours. I think it's safe to assume that We Learn A Valuable Lesson About Life. Either tolerance for others, or killing all others who are different. 50/50 chance.
