Override: Mech City Brawl

Each character has 1 skin that is locked behind a paywall. You have to buy the $8.99 skin pack for the dlc skin. The skin pack is called Override: Mech City Brawl - Super Charged Skin Pack. The skin pack will give you access to all skins for all your available mechs except for the infected skin. You will have to buy the infected skin for $1500 credits.

If the achievement does not unlock for you try this.

1) Press the Xbox guide button and highlight over the Override game
2) Click start, and then manage game and add ons
3) Scroll down to Saved Data and click A
4) Click the button Delete All, and then Delete All again (this only deletes local content, your save is kept in the cloud)
5) Load the game up and the achievement should unlock at the main menu.

Fastest way to earn money!

Credit goes to ryuji_sakujo on PSNprofiles for this technique. It works the same on both PlayStation and Xbox. 15 second matches. A video is in the link below.
Basic steps - play a splitscreen verses match, both controllers signed into a profile.
Once the match starts, press the Xbox/home button on the second controller- go over to profile and then ‘sign out’ - this will give the win to the profile on the first controller you are grinding money/achievements for. The match end screen comes up and simply accept to play a rematch. The following rematches will instantly give you the win seeing as only one player is present. Do this for however long you like.

NOTE- Unfortunately this achievement is bugged behind needing to own the DLC character pack - that pack gives 1 skin to each of the 12 starter mechs. The latest game update will show the dlc skin as locked, keeping you from having all skins for a character. 8/ The game and DLC have been de-listed so you will need a disc copy that includes the DLC code. You will also need to reboot the game after getting the achievement requirement.

I followed a similar process to what was mentioned here and earn this without dlc.

This will only work on the disc version of the game however.

1) Get enough coins to buy every skin except the dlc skin for 1 character.
2) Buy every skin except the DLC skin for 1 character
3) Back out to the main menu so your user profile is updated
4) Switch the XBOX to offline mode
5) Uninstall the game
6) Insert the disc to the XBOX so it will install version 1.0
7) Start the game and go into the garage/play a match
8) Go back online and download the patch
9) Start the game and the achievement should pop
