Two options for you, if you’ve Earthfall to spare: Coin Shop or Steam.
I’ve got the coins to afford any title currently in the Coin Shop. Can’t get an Insurgency key or a Golf It! key, as I’ve already used my one buy for those titles, but anything else in the shop (or any combination of things, within a reasonable distance of the 7500-coin price tag on Earthfall) is yours as long as you can nab me an Earthfall key.
I also have a handful of extra Steam keys for the following games:
- Abyss Odyssey
- Air Brawl
- Dust: An Elysian Tale
- Forge Quest
- Murder Miners
- RUNNING WITH RIFLES
Will trade any of these for an Earthfall key (possibly more than one key for Earthfall; depends on your offer).
Looking for one additional Earthfall key (got one willing trader already). PM me if you’re interested!
