Editing Warhammer 40,000: Space Marine (section)

== How to spam Chaos Unleashed Exterminatus ==
This DLC added IG and SPESS MAHREENS to your Ork hordes, while allowing you to be HERETICS. Sounds awful, right? WRONG. This mode is actually easy to spam to the bonus wave.
STEP 1: if you manage to get a full four players, divide yourselves among Raptors and Tacticals. (With a minimum of one raptor, but preferably two or three)
STEP 1.5: If you're a raptor, have the perks for damage when you lift off and land on with your jump pack, and a daemon maul or chain axe if you don't like the low swing speed of the maul. (not required but it helps.)
If you're a/the tactical marine, have the teleport homer and perk that allows an extra weapon. Have a bolter, melta gun, and plasma gun. (Again, not required but it helps)
STEP 2: When you enter the map, have one raptor jump to the Orks, and the other jump to the IG forces, while the tactical marines camp in a corner of the map of their choice. 
STEP 3: Have the raptors bait the two forces together, kill a few if you're feeling ballsy, and jump away back to the tacticals. The Orks and IG should start beating the fuck out of each other while only a few stragglers chase your gang. Kill the ones that follow you (it will still be a pretty steady stream, but the majority of their forces will be Shooting/chopping each other. )
STEP 4: The IG WILL win once teh SPESS MAHREENS show up. But usually they'll only have a small squads worth of either. You now have two options. 
1: have the raptors charge to draw fire, toss grenades, do some damage and leave, while the tacticals charge and blow them up with their meltas, should ammo run out, use fully charged plasma shots. then have them run. repeat until all forces are destroyed.  
OR
2: All of you run in from different directions, If you've beaten the main game 1 marine and a guardsmen or two isn't difficult, hopefully (sometimes the AI will still charge one guy, ignoring targets that are closer) they will be split up enough for each player to take out his group and help the others who haven't. 
These work all the way up to the bonus round, which is just killa kans. 
NOTE: These require some pretty good amounts or coordination between your squad members, and due to the AI's nature have a chance of entering an "allies of desperation" pseudo alliance and zerg-rushing your squad while only minimally chopping each other, this is rare however and the above strategies work 9 times out of ten.  
ONE PLAYER METHOD.     
STEP 1: Be a raptor with the above described perks and equipment (Much more essential this time.)
Step 2: Basically the same as the other step 2, except you're only choosing one side (usually the orks, they'll chase you longer) and leading them to the other
Step 3: 9 out of ten on the maps have tiny rock outcroppings or similar that you can jump up to and are inaccessible to everything else. jump to one of these, If you don't know where one is, just go to the side of the map. 
Step 4: When the IG win you need to do some scouting, usually the AI marines don't clump together, so find an isolated one and take him out. If they are clumped together, throw all of your grenades at them, jump in, kill one (or two if you're feeling ballsy) and jump away, there are usually one or two full refills for your grenades around the level. repeat as necessary until only Guardsmen remain, you should know how to kill a few guardsmen.
NOTE: This falls prey to the Allies of desperation flaw of the other one, if this happens you're fucked.
