When I was on GMG getting the Tomb Raider deal I brought the 10 game mystery bundle for £3.99 when I received the keys I was shocked to see an origin key for mirrors edge catalyst -:MIRRORSEDGECATALYSTORIGIN:FXH9-CPDX-KG3P-JXTM-7GQ7
Don't bother using this key I've already done it..
Now I don't know if everyone will get the same games as I did but for £3.99 it's worth a try..
Just in case you were wondering what the other games are I will list them
1-Club Manager 2015
3-Age of fear 2
4-The legend of candle wind
5-ETHAN METEOR HUNTER
6-Mirrors Edge Catalyst
7-Neon Space 2
9-Bunker the underground game
Origin price for mirrors edge catalyst is £49.99 so a huge saving for anyone looking to buy this game for pc.
Cheapest I've found this game for is £19.00 on gamesdeal.com
