Buying DayZ key for Paypal or/and Halo 4 Mountain dew xp

Buying a Dayz/Arma II Operations serial key for steam

Only way to contact me is to PM me.
I am willing to pay with paypal but would prefer to give Halo 4 mountain dew as i would give 200 games for 1 key

You Will Give 200 Games For 1 Key ?

Yes 200 games, the key lets me get dayz right because i dont have arma II and operation arrowhead.
