I have three suggestions that can make this game more playable:
1. our killstreaks could upgrade more like carepackages, juggernuat, dogs, and many more.
2. instead of just having campaign and multiplayer only for 1 person, you guys could add multiplayer online featuring real teams, bigger maps, more matches to play, (infected, drop zone, etc.) and bigger teams (12v12, 24v24,etc.). basiclly, im trying to say is make it like call of duty mixed with battlefeild 3 but keep the name and allow updates. if you agree push the + and I hope my changes Happen. thnks for reading :)
