It's best to be on the computer's good side in case it takes an interest in Skynet.

The world map shows a facility with several rooms; there'll be a stereotypical 'big computer room' somewhere.

Don't forget that you can click the spaceship in the top-right to mark all areas.

We've found the computer, but it's unwilling to authorise any train departures - it's activated 'Security Protocol 304' instead.

The computer itself will tell you, but it's a lockdown that's in effect until the 'situation' has been normalised.

We can't stop this protocol without resetting the computer, but a reset will be useless without messing with the servers first.

The servers are far away from the main computer - check out the world map to see if you can find the servers.

It seems there's a trigger-happy idiot guarding the servers - do your best to not get shot!

There's a convenient trail of motor oil leading from the door to a barrel of 'stun gas'. Maybe we could set it aflame?

Well, we don't have anything that could start a fire right now, but could probably find something if we had a look around.

The people running this base may not be human, but they still wouldn't want smoke interfering with their machines.

Check places where smoking would be allowed.

After visiting the construction site, try to 'grab' the nearby hole in the wall to reach a useful area.

Your friends should help you inside - follow these hints if they do, or jump over to these hints if they don't.
