Typical Storm the House, shoot the enemies before they get the chance to destroy your base. You add gunmen, repair men, a silo, and have a wide selection of weapon upgrades. By about the 30th round if you upgraded properly you can, for the most part anyways, sit back and let your employees do the job for you. At round 40 you win, but the game let’s you continue if you want, and gives you a special bonus if you do, but I’m not going to tell you what that is, wouldn’t want to spoil the surprise.
