dunno if you're being serious, but you need to get the key off endar to move the platform to the middle, but also go to the launch control where ryan is by taking a bigass lift...... and either you or evilinvasion tells us to hit the button to open the launch doors. you're pulling my chain right?
P.S. I've noticed, if you kill endar, take his key, move the platform for the shuttle, then talk to ryan, once you exit the conversation you're stuck in 3rd person. its really weird.
