Great Game
After wasting significantly more time on this than is advisable, the earliest I could seem to get the Barrett was day seventeen, that was with six survivors a significant portion of the time. Without any other survivors the earliest I managed to get it was day nineteen.
Anyway great game. The concept is tried and true, the graphics were impressive, and the gameplay is addicting.
I have two suggestions to improve the game. First I would like to see the addition of difficulty settings, since the game gets a little easy once you have a few survivors on your side. Second I feel that the game would benefit from a survival mode, which would progress in difficulty and allow use of guns from the story mode (excluding the barrett).
Thanks for making a great game, I'm looking forward to your next submission.
