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 in non-smoking areas.

Check places where smoking wouldn't really matter.

After visiting the construction site, try to 'grab' the nearby hole in the wall.

Your friends won't help you inside - you can follow these hints if they actually do, or continue on to these hints if they don't.
