This game is amazing - I wasn't sure but bought it off the strength of the 95% review i read in a magazine.
I'v been blown away by it - The charecters and story just suck you in to a rich and atmospheric world. The compat is similar to uncharted (cover and shoot mechanic is very similar) but with squad controls built in.
The squad can be controlled simly with a d-pad command and your crosshair. Squadmates are intelligent and the AI is superb.
I normally hate this sort of thing but this is handled excellently.
I'm about 6 hours in and I know I've barely touched the game so far.
The RPG elements are handled really well with simple conversation choices and basic levelling up - Don't be put off - this is no Final Fantasy or Fall Out!!!
So far the missions are varied and really interesting - This is a shooter above all else and the action is handled really well. The battles throw twists in at every oppertunity and there is a real challenge and tactical element to the shhoting sections.
I think this is a must buy for the PS3 - It uses the Mass effect 3 engine so this looks great too - Play this in preperation (out late 2011) this is worth every penny. FANTASTIC!!!
