One Shot, One Kill
Pretty much just running through, ignoring all enemies and utilising a grenade throw to alert the guards on the tower early, hence preventing a cinematic from playing.

Weaken The Regime
A nightmare to run, two minutes are entirely scripted and the rest is pretty simple but then you come to an invisible wall that you have to spam-jump to get over. Not very fun.

On Your Own
Routing has changed a bit, specifically; after getting the charges. Besides that, nothing.

A Simple Rendezvous
Decided to change the route a bit, instead of going through the main entrance I go to the right, over the fence. Saves about 2-3s.

Steal From Under Their Noses (part 1)
Not much to say apart from I just don't stop, at all to kill the enemies; wung it at the end by doing a good strafe to get as far down the bridge as possible.

The End Is Near
Again, not too much has changed. However, I did discover that you can completely ignore going to the first hostage location... guess the developers really dropped the ball on that one.

The Hunt Is On
This entire level is pretty much an auto scroller, except for two-instances: firstly, the enemy vehicle at the beginning of the mission - you must destory this to progress -,
and second, the three enemies that come running up the hill, you must kill them aswell to progress. So, in essence, I triggered these things as soon as possible to get a 2:10.

The Showdown
This level isn't too interesting, what does take up a huge portion is the sniping (which I did bother to learn the triggers for). So, for the first wave you must kill 6-8 enemies (reference the run for the actual number), anyways once they are killed another group of enemies spawn, this time they are coming down the stairs on the huge digger. Upon killing these guys, another wave spawns at the trucks, killing 5 of these guys spawns more enemies at the same digger location, killing all these guys immediately causes your squad to start running up the stairs, whereby them reaching a certain a point causes the mission to end.
