When will P2P trading come to this game- i can imagine it being good as there are many players - also you could evolve the minions that way - it would work better than pokemon as trading is easier.
I think an ultimate version of every tower/ weapon should be made. They would have special effects and bonuses like "for every _____ tower you have, stun percentage increases" or something of the sort
After playing this game, I redefined the meaning of dead. Now, the meaning of dead is blown up into bitesize chunks. If it doesn't look like minced beef, it isn't dead yet.
