After finally checking responses to my last challenge map...I have decided to make a sequel...storyline is something like this:
After making it out of the tomb you are picked up by a combine patrol...not knowing what to do with you they throw you in an old abandoned jail that once was owned by a rogue combine who was story crazy...he had 1 way to get out but to do that you have to activate a series of machines and accomplish tasks (get gas, turn on pump etc...)
You will start in your jail cell...door unlocked and you have to find your way out
Sound good??
