Fortships TD

You know the rules and so do I Fortships: Conquer the Skies is required! Unrepair is required! Use the spook commander! The goal of the attacker is to destroy the current tower spot of the defender, and the goal of the defender is to survive all 18 waves. Between waves the defender may redesign his tower while the attacker builds the next wave, every three waves a boss wave occurs. Before each boss wave the attacker can research a technology building and the defender does so after the wave ends. Both players begin with a technology building aswell, wich is the avation center for the attacker. The munitions plant, the factory and the ionospheric lab can only be researched after all lower tech has been researched. After each boss wave, both players gain two TowerPower, increasing their initial five and the defender moves a towerspot forwards and can use the new TP in his redesign. TowerPower are the currency for weapons and materials, this will be explained a bit later. If the attacker succeeds with destroying the defenders tower, the wave ends immideatly. The defender builds a new tower on the towerspot behind it thus the attacker makes progress. If the attacker reaches the final towerspot, the defender has +1 TP while defending the last spot. If the last tower is destroyed the game ends and the attacker wins. About tower and Fortship creation: the tower needs to have two controllers wich indicate if the tower survives the round or not, while a wave is happening both players mayen´t place anything new, except place background bracing and delete things, also if you have TP left you can replace weapons anywhere while the wave is happening :D The wave ends after the attacker has no ships left, each ship must use at least 1TP individually. TP is used for weapons and materials, here are the exact numbers: 1TP-one weapon +1 for each technology required. (1sniper, 2mortar, 3Shotgun, 3Cannon) 1TP-2suspendium chamber (controller and first one free) 1TP-unlimited bracing (wood
