Bought the physical version of the game yesterday but it seems I'm unable to play Warzone. I got stuck on "finding Spartans" I checked my NAT and is open and I can play all of the arena modes just fine. Anyone else having the same issue? I searched online a bit and find this: http://stevivor.com/2015/10/halo-5-guardians-warzone-matchmaking-appears-to-be-down/ but it does't look like me problem. If anyone knows a fix i'll be grateful.
