You are a loyal Syndicate gunbot!

1. As a gunbot, you have two primary weapons and a radio available to you.
First, you have a semi-automatic rifle. It is capable of doing 45 damage per shot, and can fire 5 times prior to a 20 second reloading period.
Secondly, you also have a riot-suppression shotgun, firing up to 6 rubber slugs before a 30 second reloading time.
Finally, you have a radio tuned to the Syndicate Frequency, talk and listen to your fellow operatives with a message prefix of :t.

2. Your goal is to assist the Nuclear Operative team in moving and planting a nuclear device on-station.
The target location is recorded in the audio log and also viewable through the Notes verb.
If you are unsure where the target location is, check the map button in the top right of the client, or use the camera monitors on the bridge.

3. Optionally, the captain's authentication disk can be used to shorten the countdown. The Syndicate commander spawns with a special version of the pinpointer that tracks the disk instead of the nuclear bomb.

4. Teamplay is key! Discuss the mission with your comrades and come up with a solid plan before anybody heads out. Use your headset to stay in touch:

say :h I'm about to activate the nuke in security. Stick together, boys!

5. To exit the Syndicate Battlecruiser Cairngorm, take a pod from the podbay and open a wormhole leading to the station. Be aware that Pods cannot warp back to the Cairngorm.
Alternatively, stand on the teleporter pad and use your teleporter remote. This will take you to the listening post. You return to the shuttle in the same way. The station is to the north-west of the listening post.

6. To trigger the nuke:
1. Load the nuke into one of your pods and drop it off near the station.
2. Move the nuke to the designated area.
3. Click on the nuke with an empty hand to activate it. That will prompt a station-wide red alert, stating your exact location.
4. Insert the authentication disk if you have it.
5. Defend the nuke until the countdown reaches zero. It's all or nothing!
6. Gloat over the radio and vanish in a cloud of radioactive fire!
