Blow up 3 tripwires with explosives.



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 level.
- 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.

Achievement is worth 20 gamerscore.
