Survival Strategies: Parish

Here is the Parish survival map:

For regular waves I post up in the shop on the left:

Put claymores in the blue area to keep yourself safe from behind and then sit in the red area watching out towards the hovercraft.  The enemies will come in along the yellow arrows.  A few will enter the shop from behind, but not many and of the ones that do not all of them will come attack you.  For some reason they come into the shop, duck behind some cover, and then leave and circle around to the front (red circle).

For juggernaut and helicopter waves I did a loop around the whole map:

This loop passes the air support armory in case you want to buy air strikes, and also the equipment armory if you need anything else.  I would always go prone right in front of the equipment armory and get equipment, and in that position the helicopters took a solid 10-15 seconds to get into a position where they could hit me, by which time I was gone.

Parish is a Tier 5 map.
Jugg/helo waves:  4, 9, 14, 19, 24, 28, 32, 36, 40

Survival Strategies: Decommission

The Decommission survival map:

I set up sentry guns facing out the doorway of the room in the top left of the map, and claymores on the back stairs to that room, like this:

Most of the enemies during normal and helicopter waves come along the red arrows, and the claymores take care of the back stairs fairly well.  I sit at the blue/red circle with the pillars for cover, and the sentry guns do a decent job thinning out the enemies at the doorway.  For juggernaut waves it's the same looping strategy as on any other map.  The houses between the air support and the equipment armories work pretty well since there is more cover and more ins-and-outs there.

Decommission is a Tier 2 map.

Jugg waves: 9, 12, 18, 21, 27, 33, 39, 45
Helo waves: 6, 15, 24, 30, 36, 42

Survival Strategies: Off Shore

I don't actually have a coherent strategy for Off Shore, rather a few simple tips.  Here is the map:

I'll call the vantage point up the long ramp a crow's nest for convenience.

For all regular waves you can sit up in the crow's nest and do extremely well money-wise.  I've played waves 1-4 a number of times and can easily get $20,000 simply sitting up there and going for the rampage and kill streak bonuses.

Wave 4 brings a juggernaut but it's very easy to simply flash and kill him before he reaches the top of the ramp.

Wave 5 is the first wave with a helicopter and you should run around for all jugg + helo waves from there on.  The map has tons of cover and stairs and hall ways to run through for those waves.

Off Shore has a brand new wave progression.  Let's call it a Tier 6 map.

Jugg + helo waves: 4-5, 9-10, 14-15, 19-20, 24-25, 29-30, 34-35.....
