There is room for improvement. I got the impression that this game was more of a shell waiting to have more features added. You have got the basics down but apart from that there is no real appeal to the game. I would like to see (if you decide to make a sequel) more variety in the weapons, so not just the same thing different looking gun, different enemies, and the option to add more survivors or at least change their damned weapons. Also please explain what the perks do... and have at least a little bit of a story line.
This is a good game and rly well done... but it should have a warning about blood and violence before the game starts and also i spend ages trying to get his head to rip off using the ropes... it didnt come off :(
