Gears of War

From x360a: To get this achievement, you must be on the winning team in each of the original maps: Canals, Clocktower, Escalation, Fuel Depot, Gridlock, Tyro Station, War Machine, Mansion, Mausoleum, and Rooftops.

Host the maps yourself if you are having trouble, if you lose the game just re-host that map.

Even faster way: Host a boosting session on ranked matches! Set your rounds to 1 per the above stated maps! Have one person kill all three of the "opposing" team and repeat for the others who needs the achievement! (ex. 1 player from Cogs kills all three! Host repeat the session on the map and then have 1 Locust kill all three cog members.) I did this in a boosting session with 6 players and we had it done within 15-20 minutes! Repeat the process til all boosting members obtain the achievement for each of the listed maps that were posted by CAS gamer398:
Canals, Clocktower, Escalation, Fuel Depot, Gridlock, Tyro Station, War Machine, Mansion, Mausoleum, and Rooftops.

Edit: Cleaned up solution with "fancy" formatting that I didn't really know how to use when I originally posted this solution

This is a good way to get multiple achievements in one session.
This method will get 6-8 people the following achievements:

"Around the World"(ATW)

Don't Hate the Player"(DHTP)

"Mix it Up"(MIU)

"Can't Touch Me"(CTM)


way back when I got these achievements this is how the leader of the session had us go and I'm surprised this wasn't out here before so here is what I think is the best way to knock out multiple achievements in as short of time as possible.

(IMPORTANT!!! have the same people on the same teams though out the session i.e. if you were on COG for the first match stay on COG for the whole time and vise versa. This way everyone on COG will get "CTM" at the same time they get "ATW" then start over and let the Locust team do the same thing)
(Also note that if anyone needs "DHTP" that you can easily get this if you are on the team that is supposed to win, make sure to get all the kills for one match, then trade off next match until everyone has "DHTP")

1st run-though: "COG" run-though
Have someone start hosting 1 round games. I will go in alphabetical order of maps and game types but you can do them in any order as long as you catch them all. First start an Assassination match on Canals, meet in the middle and have 1 member of the COG team get all the kills to win the match (this person will get "DHTP"). Start the next match as Execution on Clocktower and have the COG team win again (switch who is killing if everyone needs "DHTP"). Start the Third match as a Warzone match on Escalation. (Everyone on COG team should get "MIU" at this point). Continue with whatever gametype you want (Assassination might be slightly quicker) for the matches on the remaining maps (Fuel Depot, Gridlock, Mansion, Mausoleum, Rooftops, Tyro Station, War Machine) at the end of the War Machine match everyone on Cog should get "ATW" and "CTM"

2nd run-though: "Locust" run-though
(make sure you keep the same teams)
This should go exactly the same as the COG run-though but for the Locust team.

Summary:
everyone can get "Around the World"(ATW), Don't Hate the Player"(DHTP), "Mix it Up"(MIU), and "Can't Touch Me"(CTM) in (20) 1 round matches.
