How to unlock the Unconventional Warfare achievement in Call of Duty: Black Ops - Definitive Guide

Load up Executive Order. Once you've secured the comm tower, you will get a checkpoint. Right afterward, you'll be given the crossbow with the explosive bolts.

Two trucks will pull up with 3 guys each. Kill them. Then in the distance, several enemies will come from behind the building. Kill them all, including the guy on the truck with the mounted gun.

When you are instructed to shoot the zipline to Weaver, instead kill yourself or reload the checkpoint. You will start again at the top of the comm tower before you get the crossbow. Rinse and repeat.

I had to play it 3 times to get it, but you might get it the second time.

(Thanks to McRhinoator 18 for the idea about killing yourself to reload faster.)

Its faster just to kill yourself by holding a grenade for too long than going back to the menus each time

Good call. Hadn't thought of that. I'll add that. Thanks!

Yeah this is what I did, but I shot a bolt on the ground and stood on it instead. Great guide+

If you're a bit late with the 'nade (like I was) and it loads up the grappling hook, then don't worry as you will get another chance.
Proceed until you are walking along the dam, about 10-15 enemies will spawn on the balcony opposite, press left on D-pad to load up the remaining explosive bolts, kill them, cook one up and repeat

You can't cook a grenade, it locks you into an odd view where you can only fire the crossbow. Usually that's a good technique though ;)

@D Fineout: Yes, you can cook grenades to kill yourself. (I know this, because I did.)

Thanks for the solution, Sashamorning.

Not sure if they patched it, but yeah - it locks you into a view where you can't do anything but shoot the zipline, and there is no option to "reload checkpoint". But you can go down the zipline anyway, and just get the people in the room to kill you to revert it.

You only get locked in if you kill all the guys. Just cook a grenade before killing them all and then you can keep farming the kills. Saving and quitting out to menu works fine too; just takes slightly longer that way.

Ya did it one 3rd try. Note you can't kill yourself when you have the crossbow however you can die after you zip line into the bunker and let them kill you here. Don't shoot at them. The CP will restart back up on the tower right before you get the cross bow.

If you accidentally succeed in zipline through the window. You're able to keep your crossbow, the explosive tips are a secondary mod that you can equip. Comes with 15 explosive arrows. Proceeding up the catwalk and waiting to get double kills is a viable option.

In the mission "Executive Order" (thanks tato br), you'll be given a crossbow with explosive bolts. sidenote, theyre really fun. after getting the crossbow, you need to take out the vehicles so your team can move in. you wont get the 30 kills here unless you pull off a miracle. keep advancing in the mission, the crossbow will be your secondary until you change it.

you can get 30 kills in any other mission with the explosive bolts, but i found this to be the easiest.

Also, you can die after you zip line into that building where Weaver is being held and just replay the checkpoint over and over until the achievement unlocks.

Easiest level I found to get this was WMD. Use normal crossbow bolts to sneak past the first guards (which gives U the Mr.Black Ops achievement). Then switch to explosive bolts when u get into the main building. Then U get more enemies after skydiving off the cliff. Keep replaying/restarting until it pops up.

Mission 4: "Executive Order" OR "WMD"

Spiderbite from NextGenTactics will walk you through a very simple way of getting this achievement and will tell you exactly what to do.

When you are able to use the explosive crossbow, kill every enemy then kill yourself. (Easy to do on Veteran, lol.)

Each kill counts and "respawning" in the campagin stacks.

Kill 4, die kill another 4... equals 22 more to kill.

In Mission 4: Executive Order, you get a crossbow that shoots explosive bolts after clearing the Com Station. Target any enemy or space nearby and the explosion from the arrow will kill them. Kills still add to total even if you die and restart from checkpoint, especially on Veteran.

You also obtain this crossbow in Mission 11: WMD but I wouldn’t recommend using explosive bolts so you can remain stealthy and avoid drawing attention, allowing you to complete the level easier.

On the mission "Executive Order" get to the part where Woods gives you the crossbow. Shoot everyone on the ground and after you grapple just cook a grenade to die and respawn on the crossbow section again. This strategy took me 3 respawns and should take roughly 3-4.

During the mission "Executive Order", you will be given the crossbow with explosive bolts to kill off enemies attacking you from below. Aim at the vehicles. Once you have eliminated these enemies, you zip line down to the building and you will start facing even more enemies. To use the explosive bolts you must press . There are plenty of enemies to kill during the level, so you shouldn't have any trouble doing this in one go. You don't directly have to stick each enemy. If an enemy dies from the explosion, it counts as a kill.

Everything here is clear and simple. If my memory serves me correctly, there is a crossbow with explosive arrows in 2 missions. These are “Special Task” and “WMD”. You have 20 arrows at your disposal and you can even get these 30 enemies in 1 mission.
