VERSUS MEDALS
5
VENGEFUL102050100A nemesis is an enemy who killed you 5 times in a row without you killing him in the same match. I don't have a super good method for this, I have been using 2 controllers and killed myself with the 2nd controller 5 times then executed the 2nd controller.
6
Execute (#) nemeses.
7
CAPTOR502005001000Press X while standing next to a downed enemy to take them as captive, you can only use melee and your pistol like this. You can knock out a great deal of these while going for leader captures.
8
Kill () enemies with a captive.
9
WAR SUPPORTER5102030Weird medal, been reported to unlock in private matches with different settings. The correct way to earn it is to play online during 30 different Gears Events, to check what events are comming up, go to the "Event Calendar" option in the main menu.

12
Earn () MVP ribbons.
13
FIELD SERVICE255075100You gain EXP from pretty much everything in Gears 3. You get the most points out of playing Ranked Matches, however expect your opponents to be more skilled than in quick match. If you don't turn off your console you never lose your consecutive bonus either.
14
Reach Level ().
15
VETERAN100100020004000Create a private match of Execution or Warzone, set it to 1 minute and fill it with bots. Make sure your controller doesn't go inactive by using a wired one or a battery charger cable. If you don't have any cables you can pull out your battery pack during the countdown screen before th matches begin. Go sleep or go to school/work and when you come back you'll have tons of matches played.
16
Play () matches.
17
MATCH WINNER5050010003000Same as "VETERAN" except you can play the matches yourself if you really want to win every one of them. You can also plug in a 2nd controller for the other team to even out the odds.
18
Win () matches.
19
HEADSHOT10050020004000You can score headshots with most single-fire weapons. Easiest for me is to down someone, then fire 2 rounds in their head with the snub pistol.
20
Get () headshots.
21
HEAVY WEAPONS10050020006000One-shot, Mulcher and Mortar counts as heavy weapons.

28
Skunk enemy team () times.
29
LEADER1050150300You get the untouchable ribbon by finnishing a round of CTL as leader without letting the enemy capture you at all. There is a trick to make you leader every round, you need to have 2 controllers and a dummy profile. Make your dummy profile the main player by pressing start with the 2nd controller at the "PRESS START"-screen, this will make your dummy profile the main player and you the secondary player. Start a match of CTL with rounds to win at 1 and cap time at 10, the key here is to put both you and your dummy profile on the same team vs 5 bots. The first match you start will have the dummy as a leader but every match after that you will be the leader! Must be done with bots set to "Fill" or in a match full of players.
30
Earn () Untouchable ribbons.

34
Get () assists in Versus multiplayer.
35
MEDIC502506001200Press X while standing next to a downed teammate. These will most likely come while going for all the other medals, just revive whenver you have the chance. If you really want to knock these out fast, play CTL with bots and turn friendly fire on. Keep hitting/shooting your leader till he goes down, then revive him, rinse and repeat.
36
Revive () squadmates.
37
COVER1050300600You earn the Buttoned Up ribbon by spending the most time in cover in a match, using a meat shield will also count as cover.
