Objective: finish the N7 challenges!

This is my build. So yeah nah, no juicy techbursts ,or any other combos for that matter, for me.

AR is indeed is my oh shit button, also used for some general relocation comfort.  Offense wise, since its  the Targetting VI, it doesn't really matter what weapon i'm focusing on, it really is quite situational and depends on my mood i start the run in. normally whichever i get frist medal i tend to go with from there on.

- Dragoons are indeed easy, a CS to stagger followed by a Mantis headshot. i cackle every time explosive ammo's secondary explosion finishes them off. Found out that the VI III is superior to SR III in this scenario damage wise as well. And in a close proximity scenarios i.e. escorts or during wave 4 fun times that the mattock is a tad easier... No need to scope simply CS, frag, frag, and just tidy up what's left of them goons and phantoms.

- Single phantoms are manageable in a direct confrontation like you said, keep them suppressed with CSs, when dealing with multiples preference is to relocate to a safer spot to return fire. that's where the two frags tossed out of AR are just enough to get them of my case by either bubbling them up or forcing them seek cover due to the direct damage or frag dot.

Moving/camping wise, and let's use a tad more detailed map from our resource library shall we, yep same as yours really, operations is the primary camping base (happy wallhax time) at around (15,22) until overrun/pushed out, and generally maintain moving counterclockwise pattern, at first relocate onto the (5,20) ammo box, more wallhax, from there either circle about back to operations or retreat south and then east via the EZ hugging the map boundary to avoid crossfire and plenty of lateral movement to confuse turrets, camp again at around (26,16) as long as i can then move north past the structure and back to operations via the ramp.

a couple more random observations...

- parking at that wallhax spot at (15,22) seems to confuse mook AI it seems, with them congregating at the other side of the wall at about (8,21)-ish  - easy pickigns.
- whilst it's tempting to jump off at about (10,11) while kiting need to be careful, a particularly sticky offramp (yep, that's right, a sincere fuck you omnibutton) there.
- the locale at (16,18) is another congestion area, if you're lucky you can get a bunch tied up there at later waves eaning you don't have to deal with the whole spawn.
- grabs are very easilty done during wave 1 by heading over to (26,14) once the budget is exhausted, you're most likely end up with 4-5 troopers/centurions and 1-2 nemeses. the former will politely get in line to get grabbed and then if still short cat and mouse with the latter will net you the shortfall
