Mission 61 of 90Story mission
The second of Derrick's names is Aiden O'Malley, who is in a prison transport going through the Booth Tunnel. The plan is to block the tunnel with a truck, take the Stockade, and drive Aiden somewhere quiet.
It is the only way in the game to get hold of a police Stockade, and it ends with a cold execution the player has to carry out.
Packie leaves it in Alderney City with a rocket launcher in it. Drive it to the Booth Tunnel and put it across the road rather than beside it.
The instruction is to destroy the escort and keep Aiden alive. The launcher answers the police cars nearest the blockage; the officers on foot are quicker with something fully automatic.
Take the van once the escort is down. Three stars come with it, and the van is armoured and slow — so shed the level by getting out of the search area rather than by trying to outrun anybody in it.
Ditch the van, take an ordinary car and drive Aiden out to the cliffs in Leftwood. Anybody who wants to keep the Stockade should store it before finishing.
Who this mission brings together, and the ground it covers.
