Fortress Survival Alpha 4.50

Hey! Thanks for playing, on behalf of the Fortress Survival Team, i'd like to personally thank you for sticking by us! Yes, we are offically back and we have a totally new map for you to check out! New modes, units, towers, and best of all, new terrain! Now its really like a fortess! Please Note: This map is currently a beta, if you are playing this, either Nevo likes you so much that he let you test it out early, or you just happened to find the map, eitherway, good luck, have fun, and base wisely!
