Part 73

Lead the riot police into Soho and defeat/arrest the first group of rioters. (While using the baton you cannot cuff suspects).

Progress to the next waypoint. (Gab a pork bun from the street vendor if you need one).

Arrest/defeat the next group then defeat further enemies for one minute.

Collect the tear-gas grenade-launcher from the trunk of the police cruiser. (You use the normal gun controls: L2 aim, R2 fire, R1 reload and L1 cover (press the cover button to crouch behind walls or objects); you can also tap Square for melee attacks while carrying the launcher).

Continue to the next waypoint along the road.

Use the tear-gas to suppress the crowd there.

Head upstairs, over the travelator to the plaza and repeat. (If you're obsessive about completing the stat awards this is the time to get the Gassed one - keep gassing the guys without gasmasks, you can score several times off each one; once the crowd starts looking a bit sparse just use the pause menu option to restart from the checkpoint (an auto-save point you restart from on death) and repeat until you have the Gold award; also watch out for the big guys stealing your launcher off you!).

Defeat further enemies for one minute.

Defeat the vehicular enemies in an on-rails shooter sequence. (Use careful aim with the shotgun and avoid shooting their van in front).

Kill all the targets around the three dockside waypoints (you have an SMG). (Collect ammo from your victims, fill your Face meter to heal, check the map for enemy locations and move closer if your shoots are ineffective). (There's an EVIDENCE BAG on the covered roof of a large houseboat near the centre of the harbour area but it's a pain to get to - you need to climb onto the roof of a boat to the south-east then jump across three rooftops to get over to the big houseboat with the collectible on it).

Take out the hostile targets (you start with an assault rifle this time). (Use controlled bursts, go for headshots for quick kills and if you use your car for cover watch out for it catching fire!).

Defend your position for two minutes (just stay alive basically).

Drive over to Aberdeen harbour.

Defend the boat in an on-rails shooter segment.

Kill the first group of cultists on the south casino barge. (Go to the south-west corner and down the stairs for another EVIDENCE BAG - if you grab this one now it'll save you the hassle of coming back later).

Replenish your ammo then take up position on the waypoint.

Defeat the second wave that appear behind you then head inside.

Arrest the master of the cult (who was barely even introduced previously).
