Seeing as everyday when I come and check the forums, I always see gearheads asking for help getting a full 5-man team to get these 2 achievements. So why not make a thread (and if possibly a sticky ) on tips on how to get both achievements fast and easy.
Come to Poppa!
Won a versus multiplayer match as a team of five Recruit Claytons (any mode)
Won a versus multiplayer match as a team of five Savage Marauders (any mode)
These are both easy to get if not for the five man requirement but miraculously, there is a work around especially if you don't have many friends in xbl.
So here goes:
If you have a spare controller, log in as guest. ( credits to @kylempcp) or....invite 1 player to get both achievements and follow these simple steps:
1. Use spare controller and log in as guest or Invite 1 player (Someone who has the Forces of Nature DLC)
2. Both of you (duh) equip Recruit Carmine skin for COG and Savage Marauder skin for Locust
3. Go to - Versus - Forces of Nature - Brothers to the End mode (it negates the 5 man team that is needed, trust me. I got this using this technique)
4. Play and WIN matches using both skins (you have to win in order for the achievement to unlock)
5. Get the achievements
6. Have fun with this awesome game!
So there you have it folks! Simple and easy to get.
Hope these tips would help everyone in acquiring both achievements in no time.
