Tense FPS and rough around the edges
The maps i like them alot and i think they were laid out well but minus the open areas it can get claustraphobic but there are plenty of places to hide.
SOME of the gun sounds i think are too flat on the reverb. I am a gun owner and even a pistol shot in doors can sound like a cannon and kicks impressively. So i have to say the gun sounds close up are to tinny (not all guns) - from far away they sound GREAT and powerful however.
Also i notice that you can hear boot sounds on snow and in certain places BUT in other areas a guy can walk right up on you soft as a cat with narry a pebble scrape or crunch or anything. Also grenades dont make a sound when they physically bounce off a surface which can lead to some surpises.
I had some minor graphical errors like tearing geometry in game and my menus are BLANK so i have to guess at some of the controls. The maps themselves are well populated structure-wise and for a city scape well done for the amount of accessible rooms and views.
OVERALL - if you loved RO your going to like this because its a niche game for specific types of players. The graphics and sfx are rough around the edges BUT far from displeasing. There seems to be some lag issues but not terribly so.
