Average steam user, plays Half-life 2 mods, left 4 dead 2, call of duty modern warfare 2, and is a mapper. I have made some counter-strike:source, Day of defeat maps along with a Left 4 dead campaign
Just the pre-release media warrants a 10/10 The devs deserve the praise for the hard work they've done
Very original, very fun, and i see a LOT of great potential for this mod in the long run.
Single Player review:
Not good at all, first of all, the skins for all the weapons are not yours, they are all downloaded either from fpsbanana or some other website. I mean a katana... really? there is no real story or anything that really resembles a story, buggy with repeating sounds and enemies appearing and disappearing in front of you. Not scary at all if that was what you were trying to achieve with some of the maps and seems you didn't spend that much time planning the layout and they feel very bland, generic and boring. The climax to the helicopter is hardly climatic and with enemies randomly appearing from nowhere was just a very poorly made finale.
I know this is your first mod but you should really work longer on things like this if you want to make something worth other people playing.
