This guide is for all extinction trophies. To start it is an absolute must you have a party of four who not only have mics but communicate as well. It is also advised to have everyone at least level 22, in case of the throttled escape trophy you must have prestiged at least once (level 31) then under your loadout you'll see the relics. The no class is the easier one to do. If you are going for this replace a tank class for this. Concentrate on completing every challenge, do whatever it takes to complete them. As for load outs the following is recommended
1 medic. max class, max sentry, level 2 pistol, max reg ammo
1 engineer max armor, max feral, level 2 pistol, max class, max sentry
2 tanks
1st. max armor piercing ammo, max sentry, level 2 pistol
2nd. max sentry, max booster, level 2 pistol, max class
Whatever skill points are left over keep putting them in each skill. Just concentrate at sentry guns, ammo, armor, class and riot shields are useful if you have it equipped to protect your back.
first hive is either going to be take no damage or mêlée only. Search area before planting you'll find two pickups, hopefully one is a flare. Keep working on the hives n challenges. Dont buy any weapons unless its a weapon challenge then just two of you buy that gun. Now after you destroy four hives, counting the one by helicopter, you'll have the big hive that the copter shoots at. Gather all propane tanks, throw them on the hive. Place 2-3 sentry guns facing away from hive. Wait till the health meter shows up and if anyone has a soflam call them in. With the armor piercing ammo start shooting hive. After its destroyed you'll see a money box where you'll get $3000. Since you can only carry $6k max, if you have over $3k drop ammo, armor, etc to $3k before u pick up money.
the town is the same thing. 3 hives then mother hive. I'd recommend buying the M27 LMG. its located by first hive on street on wooden platform. Keep completing challenges. Always remember to keep ammo, armor, some boosters deployed at all times. For mother hive have 3-5 sentry guns by hive facing away. Arm 3 electric fences. Everyone shoot at hive. Wont take long to destroy this way.
Working your way to the cabin you might run across two rhinos. DO NOT shoot, they will go away if you leave them alone and dont get to close. In this area its very vital to set your sentrys, armor, ammo before planting bomb. First hive you'll have a rhino spawn about 50% thru drilling. Take him out quick. There are three hives total before crater. Two on ground, one in barn. Put sentry guns in each corner of barn.
once on crater there are two hives. On the second it is very critical that all sentry guns are deployed with overlapping fields of fire. Ammo, armor, boosters need to be deployed always. Congrats you just destroyed them all, now comes the fun part.
BEFORE you arm the nuke. Everyone go to the cabin area. If you still have sentry guns out, bring them. At the cabin along the path, where theres an overhead wooden bridge, drop a sentry gun facing crater. Move down the road back to town. Before you reach the town there is that alley that goes from town to cabin. There will be a meteor that blocks you're path for 30 seconds. Deploy three sentry guns here facing towards cabin. Now move thru town. Where the road curves to take you back to motel area, drop another sentry gun by guard rails facing towards town. Now everyone run back to nuke. Make sure everyone has their pistols out. Deploy feral booster, grab it. Arm nuke then run, run, run. DO NOT bother shooting anything till you get to first meteor. Switch to main guns. Take out the two tanks quickly, and any other creatures. Deploy boosters n armor. As soon as meteor is gone, switch to pistol n run. When you get to next meteor drop two more sentrys facing town, three facing meteor. Switch to guns and kill both tanks. Deploy armor, feral booster. Switch to pistols and do some more running to extract. You should make it with 1:30-1:45 left on clock.
