Watch Dogs: Stare into the Abyss - find Crispin, kill Crispin, Infinite 92
Tactics for fighting multiple guards and killing Crispin before he escapes, and getting over to the private club Infinite 92.
Objective: Hack the ctOS box to find Crispin
When you reach the waypoint you'll see the building it guarded. Access the hacking point from across the street and hit the timed point where you'll have 15 seconds to hack.
Move the left point three times, the far right one once and unlock the point above the timed point, turning it once. Turn the far left point three times and the far right point once, unlocking the top point. Click it to access the camera.
Objective: Eliminate Crispin
Check out all the cameras in the building to see where the guards are. Crispin is heavily guarded so you're going to have to thin out the guards with violence and be wary of giving Crispin a chance to run off. Enter the south side of the building using the doors closest to him and nudge the doors open, don't open them too wide or the guards will be alerted.
Craft yourself some frag grenades and IEDs, take cover and toss the frag grenade inside. Throw the IED but wait until Crispin begins to move from cover before detonating it. If you don't kill him outright he'll run and you'll need to chase him down in a vehicle so get the timing spot-on to save yourself some hassle.
Another way to do this is to steal a car and park it in front of the open doors. Use it as cover and unleash all your firepower on the guards and Crispin, but again, be careful he doesn't make a run for it.
Objective: Hack Crispin's phone to obtain data
Objective: Kill all of Crispin's backup or escape
You need to hack Crispin's phone where ever you killed him (he drops it), and then escape any guards or back-up he's called in.
Objective: Go to the private lounge, Infinite 92
Objective: Follow the host
Objective: Leave Infinite 92
Head to the next waypoint and down the stairs. Trail the host and after a cutscene go to the door for another cutscene. Head to the final waypoint to complete the mission.
