During this level, there will be plenty of tripwires; 6 in total. You must destroy at least 3 of them with grenades (frag grenades or the grenade launcher attachment). Their locations are as follows:
- Near the very start of the leve
- In the building with the turrets, on the staircase inside
- In the hospital, just after going through the blue door
- In the hallway where the turret is shooting you, right side
- Just behind the turret from the previous hallway
- Just behind a blue door that you must slowly open to spot the tripwire.
Possible on any difficulty, but recruit is probably recommended to make it as easy as possible.
