Fusion Plant

Overview
The Fusion Plant is an income building originated from TC Mark II that can't be found in other games of the series. It's one of the biggest and most expensive buildings in the game and the biggest of the income buildings, generating $20 money per minute. The Fusion Plant also comes with a built-in Turret that acts exactly the same way as other turrets. Once destroyed, this building has a chance of making the crystal it was on unusable, meaning that you can't place any other plants near it, the exact chance is currently unknown, although it's speculated of being from 30% to 50%.

Usage
Just like any other income building(except the Oil Rig), the Fusion Plant is mainly used as a source of income and needs to be built near an energy crystal. Although it has an attached turret, using this as a defensive building isn't a good idea since it takes over 25 minutes to start making some profit and has a chance of ruining the crystal it's on if destroyed.

When making these, the best strategy is to wait until you have enough money(not late-game, since it probably won't make any profit, neither early-game, since you won't have any money for other buildings or units) and build it. Make sure that you have a decent army and that you can quickly defend this once it gets attacked.
