Nuclear Operative
Congratulations! you have been chosen to be a member of (insert random organisation here)You, brave agent, must retrieve the Nuclear Authentication disk and activate the Nuclear weapon on-board your shuttle with it. Did we mention this was a suicide misson? No? Whoops!
Red Mean Syndicate Machine
You and your fellow operatives spawn on the Syndicate Shuttle. Here, you have a load of gear to help you acquire the disk and kill everyone. You start with a revolver, a Syndicate Teleporter, a poison pill, and some ammunition. Take off your helmet and body armour and put on one of the red spacesuits from the lockers. Also take a jetpack and breath mask, and make sure you turn on your air supply. From another locker, you should get a pinpointer and turn it on. An arrow will appear on it, pointing in the general direction of the disk. There's also a Station Bounced Radio that will let you request a limited selection of Syndicate gear to help you. Remember, those items are for EVERYONE, so be nice and share with your fellow operatives. You've also got a secure radio channel for speaking to your comrades, accessed by putting ":h" in front of your message.
Get dat fukken disk
It spawns in the Captain's pocket. Your job is to follow your pinpointer to it, get it, and come back to the shuttle. The Captain is armed and Security will be all over your asses as soon as they hear about red spacesuits, so be quick and strike true. Work together with your allies if they aren't idiots. To exit the shuttle, stand on the teleporter pad and use your Syndicate teleporter. You return to the shuttle in the same way. The station is to the left.
I GOT IT
Great! Now get the fuck out of there before someone shoots you. Head back to the shuttle and head to the south end of it. The nuke is there. Right click it and select "make deployable", then click it with an empty hand. A window will pop up. Holding the disk, click the line of minus signs in the window to insert the disk. Now, head to your left and grab the audio log. Play it. It will tell you the activation code. Enter the numbers into the window and then click the E. Then set the timer, gloat over the radio and vanish in a cloud of radioactive fire.
