Gears of War: Judgment

you can get this with 1 other person with friendly fire turned on,the person who is not host must put all there character skins for all characters to the UIR skin.Now take note of the players on each team as it seems the bots can only have 2 of the same person on the same team(ie 2 female onyx).Then once the match has started the non host can quit & the bot will stay in the UIR skin.Just keep quiting & rejoining with different bots having the host kill the bot without the UIR skin on your team when it says -blah blah has joined & is waiting for a bot death-,if you time it right they will join your team if not choose the same character twice for the other team then the third time they should be on your team.Did this last night in about 30mins with 1 other player to do all 3 game modes.Credit for this sneaky tactic goes to my man Ozjay11.Yes a bit of mucking around but if you cant find the players it can be done this way.

Edit: Thanks to --ED E Nigma-- for reminding me that this also works for --You looking at me--achievement

For those who do not want to get this in a private match but rather through public gameplay:

With your team of 5 players with the proper skin on, have the host search for games under the "DLC" playlist. Note that this is seperate from the VIP playlist. We found hardly anyone plays the DLC playlists (DLC TDM, DLC DOM, etc.) so you will most likely get paired up against a team of bots. Beat the bots quickly and repeat for all three gamertypes!
