Looks like candy for me , but it seems my PC most probably won't handle it. Depends on how good the game can be customized , like quake live where you change everything to look like legoland and make the game run on a complete garbage if you wish so. 
Well yeah... minimal requirements are kinda high unfortunately

looks like the unreal engine
It is Unreal engine 3 indeed.
the graphics and the gameplay look like poop and there are already a thousand games just like this one so nothing special.
Nope. Actually this game (as whole series to be honest) is quite innovative. It's not run and shoot. It's slideeee and shoot. Movement mechanics are adding a lot into gameplay. You're equiped with jetpack with limited renewable energy and skiing boots.
With jetpack you can climb on some mountain and then skii at huge speed from it. Then there is shooting model where you can skii forward while sending bullets or discs behind you at chasing you enemy. Other thing is part of your velocity (I guess it was set to 1/2) is added to your projectiles to aiming can be really tricky. Believe me it's not generic FPS that you can see everywhere.
