Chaos, you can buy large scrap metal boxes, I use those a lot in my strategy in the mid game, where you get those armor piercing lasers. Just go with 1 heavy tank, not neccessarily armored, maybe equip him with a sword and shield, with achilles legs, and range adders and armor piercing lasor deathgunbots. Those beat practically everything, and with the scrap boxes you can inject a boost if the enemy attacks on two lanes.
Cryzer the kitty is used as a key in level 25 to a secret area.But it contains a baby pedobear so grab some of those seemingly pointless censornotes you find on the table in level 3 if you want to enter.
Jyo don't friggin rate it down because it has a badge which because of the jerks is hard to get. If it did NOT have that badge you would care less and would rate it a 4.
Also why is everyone bothering on the multi? I manage with the skirmish.
