This is a really good game on PC

Been playing for a few hours now.
It rare in 2011 PC Gamers have something which is taking advantage of their modern hardware. It supports DX9/10/11 has a lot of graphical options & also looks very good in places. FPS is insane even with max everything & MSAAx8 no frame drops no stuttering very fast loading times technically its superb & highly polished. Menus are also very fast/smooth this game is very well optimised I do not think many CPU/GPU combo's from the last 3 years will struggle with this game at all THQ/Volition did an excellent job here
The graphics are pretty special

in places & the level of random destruction is amazing its like you are in control of a big budget action movie when you fire the impressive weapons (some of the best I have ever seen in any game on any platform

). Some graphics you can see the usual console low resolution lack of detail but several are excellent & it has little graphical detail touches only the PC can render but screenshots will not really show you how impressive they are like little multicloured shaders beneath steel surfaces scattering the light with a nice rainbow pattern. Or lens flares/coloured shadow lights which form subtle glows.
For me this is one of the best looking PC games this year so far & superb technically
Controls are very easy as well. 360 gamepad is best & very smooth to play with but it supports mouse+kb as well & you can cnofigure the controls to your preference.
Gameplay is similar to RFG except now most missions take place under the surface of Mars & you get to battle some very imaginative creatures/monsters which look pretty unique. There are some very cool gameplay features like destroy a building/platform/ledge then reconstruct it instantly but watch it go back together piece by piece polygon by polygon

Its a very impressive ingame feature & you can use it anytime on objects which allow it (usually anything made of steel). Weapons are easy to upgrade & you can even reset your upgrades ingame & reallocate them to other weapons/powers. you can also save anywhere anytime & it uses checkpoints as well so you never lose much progress if you get killed.
This also has other gampelay modes apart from SP missions including a free roam destroy anything mode

& a MP game system as well.
The only downside to this game I can find is the missions are similar like most modern games. Apart from that its a game which few will regret buying as it offers more of the same as RFG but with better gfx & a much smoother gameplay experience now the action has moved under the surface into smaller play areas instead of the huge martian surface from RFG.
As its a Steamworks title it also supports cloud saves but the game will not install from DVD so here is what you have to do:
Install from DVD but you will notice it ignored the DVD & starts to download 8GB so just cancel that update in Steam then delete the game from within Steam or program files & try again this time it will take & pick up the DVD & install from there which takes around 10 mins vs how long to download 8GB!
