I found the best method was too hide behind the dodgem cars and crouch down. The enemies will run toward you one by one and you can just pick em off. the only hard bit is carrying your mate, but if you throw some flash bangs it seems to work.

Malo, I'm also on the level with the timer.
First you go through the air ducts and your first checkpoint is obviously once you drop out the air vents in the toilets.
I proceeded left, took out hte enemies, went through the corridor, and got to the area where you see a big sort of emblem on the wall on whats a staircase area going down. I have this checkpoint.
The next part is a very long corridor with a option to veer off left or right. I chose right and worked my way around to the Red Area or next checkpoint. This part is where I am stuck. Its basically a straight corridor with a option mid way to go left or right, both are tunnells that look like spirals. I cant get past here. Any tips for this bit. As I run down one tunnel, the guys in the other tunnel take me out.
I've tried to take out the guys dead ahead first with my sniper. Then try throwing flash bangs into the side tunnels, but miracuously they dont get blinded by flash bangs at all, unless you can see the enemy.

Any tips?
