Tech Wrench


The tech tree is a set of purchasable upgrades that unlocks new abilities or improves other stats for the player and their units. All upgrades are bought with Tech Points, earned at the end of each level or by earning achievements and cashing in the rewards for them. Upgrades must have their pre-requisites purchased in order to unlock the next ones.

The tech tree is split into 2 branches which then split into other branches, and sometimes connect back into single branches again. Because of its complex design, the actual path of the tech tree cannot be recreated. Upgrades will be listed from left to right, starting with the top upgrade and working down.
