Once you've finished 15, run back out and pick up the sentries, run over to Z17, and set up sentries at the bottom of the stairs there too. Its layout is such that you will still have sleeper spawns forced to run past the sentries as long as at least one person stays in the main, central room of Z15, which helps a lot. Open it, rush the cell into the generator before the first wave gets there. Put sentries at the bottom of the stairs up to Z14.

You want to first power up both doors, and finish the team scan on each, without opening the doors.

Carrying cells around sucks, it takes away a set of guns.

Each zone's layout is especially relevant for the previous point.

Sleepers must always spawn 2 rooms away from you (with some minor exceptions that are irrelevant here).Each zone you open adds another 4-per-30 enemy wave.There's a few quirks to keep in mind here: It was giving me a lot of trouble at first, but the moment I realized I didn't have to do that, I finished it on the very first attempt - with bots. I not even mentioned the containers since that part is already well detailed on other comments, mine are just for the last part.ĭon't try to go all the way down one wing. On the crazy alarm once the scan ends clear last wave, music will calm down a bit, that is when you move to the next area, be organised and calm you will have to make another full team scan while enemies will spawn but if you follow this tips, it should be fine.Īlso take as much as possible bioscan speed booster, this one really helps This level should not take more than 40 min to clear if all goes well. Save the door, once this is done, close the door to extract put down the last sentry and defend while extracting. Let the guy with the foam keep foaming the door while the others clear the extraction area and leave one sentroe outside. Save a couple charges of foam for the door before the one you need to open for extracting. On THE alarm stay inside the circle to one of the sides all of you, foam the stairs where you will funnel the enemies, put both sentries one pointing to 75 another to 130 and give all the tool refills to the mine guy and let him put mines all over the main doors where enemies spawn. Keep calm, 1 Hel shotguns, 1 thermal, 2 machine guns, 2 burst sentries, 1 mine, 1 c-foam, keep calm.
