Dead Effect 2

Mission 3

Personally I found this a pain. I was having trouble with getting the soldiers to come closer or spawn in quick enough. So....

I had bullet time equipped and upgraded as much as i could. After defeating the combat drone you are tasked with pulling a lever. As you go to that room 3 cyberdogs will spawn. Ignore them and let them run out of the corridor.

Now run down the corridor and hit to pull the lever ignoring that zombie for now. Get back to the corridor and ignore the cyberdogs. Now activate bullet time ad kill the 3 cyberdogs and zombie as quick as you can. Now head out the door asap and kill the cyberdog on the stairs to the right of where you come out of that door and another will come down the stairs to your left.

This may take a couple of tries as I think using the turret was harder. Hope this helps.

after trying both ways best way i found get a high level grenade launcher get the three dogs following you kill the zombie activate the generator get the three dogs following out to room then another 2 dogs join get them all grouped together then let rip with the launcher got it first
here a video to give you a idea how it is done please note not my video

Easiest way after trying other solutions about 20 times!

Got it first try using my method.

3rd mission ( All aboard the meridian express)

Fully level the stasis and devastation skill, worked out around 180k damage for it.
It is a ground pound attack that deals massive damage all around you.

After killing the drone run towards the objective down the stairs and get the big ugly dogs to chase you out, get some distance then run in and pull the lever...run out and keep running around until the 4 dog things and zombie are all around you, stasis can help slow any incoming damage...ground pound as it were and its an instant kill on ALL 5 enemies...finish the level and pop!
