tips to help with strategy - 1) if you surround your walls with 4-6 shield towers, they are almost unbreakable - 2) upgrade your AA cannons to level 2 as soon as possible - 3)tesla towers do a ridiculous amount of damage, use stun guns to get irradiators, and use irradiators to get teslas. - 4) the air units actually come from the side that the ground enimies come from 5) if you cant get perfect on an early level, wait until you beat the game to get perfect because the Challenge upgrades (such as faster rotation speed, +$100 at the beginning, -10% of tower costs, regenerating walls, and faster fire rate) will help greatly in most cases. 6) always build cannons to avoid problems with Jammers. -=-=-=-=-=- Upvote so everyone knows about these tricks ive loved this game for a very long time and ive finally beaten it today
