Help with "getting chunky" achivement

[^6Tallguy]

Hi as the title says, I need some help or tips for getting the "getting chunky" achievement which is Obliterate 10 Zeds at once with the Pipe Bomb. I have played solo to try to horde them up and drop a pipe bomb in the middle of the group but I can't seem to get 10 at once. Any map or strategy that might make it easier? ^^

Get a group on West London and weld the door at the church, and then place a pipe bomb behind the door. Once they break the door all of them should get blown up by your pipe bomb.

I play sp all the time, I have this achievement- the main thing with explosives is avoid open areas for setting your explosive traps- as halls and tight spaces bring more damage with the explosions, biotics lab, moonbase, hospital horrors, others-- those were my favorites when I'm demo, but any map really with a lot of narrow spaces/enclosed partially like halls or underground corridors will work fine. I like putting mine in the middle of a hall, so several are already walking through it piling up, then one steps on it and bam- chunks and red mist everywhere :)

Moonbase might be easier for someone new, since it's a small map with lots of small tight halls. When done with the trader, before the next wave comes, set a few in different halls/partially closed areas, I did this repeatedly on this map in high traffic areas (halls, doorways, ect.) to get the achievement for killing 1,000 zeds with pipebombs. Just an idea. :) Good luck.

arcade gas station ... weld doors and get on roof. If you crouch you can go up to an edge and not fall off, go above door and when enough pile up drop a pipe and back away. Other than that any map you can kite and weld doors up, get a bunch followig you then just place a pipe on the other side when they break the door down, BOOM
