You craft down so you can have more. There are perc tiers.
At a certain amount of perc, you can't get lower tiers. Each tier can only be used once every 4 hours, but you can use one from each tier. This allows you to pot up for a lot more than you would be able to with just the highest pot.
This seems like the only decent danmaku game on Kongregate. It's pretty good. The only thing that bothers me is the randomness. In many danmaku games, attacks are structured, but when the enemies attack me in this game, half the time I don't get attacked at all while the other half, I'm faced with a wall of bullets. It gets boring when all the bullets just go around me because they're too random. The story is "Meh", the enemies are endearing and the artwork is pretty good. 3/5, would play again.
The problem with Wolf Pack is that it's highly situational. Even though it adds more soldiers to the field, it doesn't count as 1 for all 3 of them. Each one costs 1. This makes you end up with a number of low soldiers and then you get wiped out by a sandworm.
I was thinking to myself, "Oh! The Remote Control, The Gauss Rifle, The Bomber Blimp and The Minigun! What could be more powerful than that!" And then I tried the Shark Gun.
