Found a couple bugs:
1.) When training with the CPU warrior, the warrior became invulnerable and I could not complete the training.
2.) After completing a CTF match and gaining the XP from it, the words disappeared from the awards I was given. I could see the +5, +50 etc, but I didn't know what I did to get them.
If this post needs to be moved, let me know. Otherwise, thoroughtly enjoying the MP Beta. Gives it the competitiveness a Spartan needs. Though... Gamestop... Leonidas spear? from 300? Really?
