one of the best units is a tanker with a lot of life (I have P-bot) and the martian gun (has freeze effect), sometimes it wiil take a while for the stronger bosses, but as long that you keep giving haste and rage theyre unbeatable
the eefects of the enemy active a lot more than just a 50% change because I have shot 10 times in a row against a flying unit and it dodged them all, but my flying units dodge 1/6 of the times
wow glitch: i got the game completed and get all sushi recipe badges when i didn't even beat wave 20 or got all sushi recipes yet. the only thing i did was get all upgrades
