Just downloaded this, 305MB.
A third person shooter, in an icy, snowy place - it looks rather good at first glance, getting used to it and it's nothing amazing, but very solid (that solidness broken by the minor screen tearing).
You can do the Resi Evil 4 style turn-around by using the top left and top right buttons for 90 degree switches. Works really well. Just running through the level shooting spider things.
The grapplehook thing (Y button) is a bit dodgy, grapples onto walls, pulls you right towards them and you go through them (well, through the ceilings then drop down).
Back to the game..
