Twist ending to BO2 is that a giant magic obelisk rises from the ground and turn all the soldiers in the world into wizards so they can dabble in sorcery.
You can use spells such as shooting ice shards along a path at people at a distance, or surrounding yourself in a ring of fire so enemies cannot knife you or they burn up to ashes. Another weapon is using pure mana to use in bursts like a shotgun but restores a percent of your health
For killstreaks you can summon a death ward that will rise from the ground and be an invincible LMG firing at people.
And you can call down a bolt of lightning that instantly kills all enemies that do not have some type of overhead protection.
Or, you can apply a buff on your teammate that makes them have an extra 200 hp for fighting.
Who else thinks this could be a good idea?
All hail the mighty woolay. http://i1115.photobucket.com/albums/k541/Muddywater10/stupid3-23.png
