I have codes to swap(gears 3 and arkham city)

hello guys,i have a spare code for catwoman bundle pack and iceberg challange maps

my question is , does anyone want to swap me something for them?

im looking for mechanic baird or savage grenadier elite for gears 3

or robin dlc bundle pack for arkham city

thank you and sorry for my english

hate to break your balls but nobody in their right mind would still have a gears 3 character code kicking around maybe the green liquid skin
