Zombie game won’t load, I get to act 1 and any mission I select it says equipped but never...

Ok here's a question about upgrades the Support class gets a deep pockets ( +1 inventory slot) at rank Major, now I don't know if this is a glitch. I tried at first to equip a second medkit it won't let me saying 1 per soldier, ok I tried equipping a grenade
it equips but in mission I cannot select it, I even tried using all the medkits first and still nothing. Has anybody else have a similar issue?

Have you completed all Missions (blue) and the Quests (storyline/pink)? I had to clear out a couple missions towards the end of Act 1 to get the next Act's Quests to start up.

call of duty playing in vetren got "stand down" the achevment for completing the game but did not get complete the game in vetren plus had other missions to do eg "escape kowloon"

saints row the third it did not give me "http://killdeckers.die" / "titanic effort "/"zombie attack" "muderbrawl 13"

you get one of two achement going through act 1 i should have "tower deffense" or "kkuh, boom"

but did get the achevments for act 3

why do i pay money for xbox ?

ps THIS BETER NOT GET ME BANNED!

I can't even get into the game from games and apps when I choose a game it goes to a load screen and then acts as of I said Xbox go home. But the game never loads.

yes. every mission says i completed it on veteran in the mission select menu. which is why i dont understand why its not unlocking. i never once touched the reduce difficulty button on the menu in game.
