Great game, easy achievements! Definately a buy!

Truely English supported
I picked up this game the day it came out. Since it being a Japanese game, I kind of expected it to have a little bit of English support but mostly everything would be in Japanese. That wasn't the case. You have the choice to choose the display language in the options menu and if your 360 is set to English it will automaticly select English in game.

The game play is very cool, a good mix of splinter cell and MG. So if you like sneaking around and sniper rifles then this game is probably for you. Unfornately this game is region coded though, so you will have to have a Japanese 360 to pick it up.

Ah, AQ Interactive...
After bringing us Tetris to the 360 you gave us the pretty but forgettable Bullet Witch. I was a little sceptical of this game but bought it anyway since it's very rare that a vampire game comes along. It's actually a good game. Very similar to Splinter Cell, imagine if Sam Fisher met Dracula, this is what would happen.

The story is simple, Los Angeles is being overrun by a vampire plague, and at the rate it is spreading, humanity is running out of time. It is known that by killing the source of the plague (the vampire elders), all vampires created by that elder vampire also die. So the objective of the game is simple, infiltrate the city, hunt down the elders, and kill them.

Controls are easy to get the hang of and gameplay is fun, but not as action-packed as a game like Quake or Gears of War. It's a much slower pace, remember it is primarily a stealth game, not a shooter.
Graphics are beautiful, easily a step up from Bullet Witch.
Recommended.

Stealth!
This game is made by AQ Interactive, the same company that made Tetris and Bullet Witch for the 360. This Japanese release, unlike Bullet Witch, has FULL English support. Just go into the menu and select it, you can then play the whole game in English.
If you are a fan of stealth games like Splinter Cell or Metal Gear Solid, this game will appeal to you. If you like run'n'gun games like Quake, Lost Planet, or FEAR, maybe you won't like it.
Basically this game involves a LOT of sneaking around, and being caught or exposed almost always equals certain death. The levels are more like huge puzzles, the objective to find a path and move through them unseen rather than explore them with heavy firepower to fall back on if you are seen. Unlike a lot of stealth games, where even if you get caught you can usually get through the mission, this game is very unforgiving. Most times being seen is a death sentence. But the game also has adjustable difficulty levels so if you are having trouble you can always play it on an easier setting.
Most levels in the game are very dark, and you have a set of night vision goggles to help you along. In addition to this you also have another set of thermal goggles which help you distinguish who is alive and who is undead.
The graphics are beautiful in this game, and the story is not bad either. Worth a look.
