As the "author" of the builds listed below, I need to explain few things.
First : All those builds have been reviewed by three different communities. The two main reddit (r/thesurgegame and r/The_Surge_Game) and the steam community (https://steamcommunity.com/app/378540/discussions/).
Second : If you have any question about a build, do no hesitate to take a look at the different section of this wiki. I believe you will find the answer of your question if it's not already explain in the build presentation.
Third : The CP showcased are exemplary threshold. They also serve for delimiting what implants can be obtained in the differents areas of the game.
I split the builds in three stages : early game (CP25/35) ; mid-game (CP45/55) ; end game (CP65/CP85)
CP25 : when you reach Central Production B
CP35 : anywhere between LU-74 'Firebug' and the Circulation Tower (+DLC A Walk in the Part first part)
CP45 : when you reach Research and Development (+DLC A Walk in the Part second part)
CP55 : right before Black Cerberus
CP65 : after Black Cerberus and back tracking to open all the Security Doors instead of going to the Executive Forum
CP75 : Executive Forum completed
Why stop at CP85 ? It is the highest Core Power required to overcharge the crates containing the Nano Cores in NG.
CP85 builds are NG+ ready.
Fourth : Please take a look at the Core Power page to understand how to improve your build through leveling.
Fifth : I intentionnaly avoided to use paid DLC content for the builds that could be made without.
The reason is that the most acquired Steam achievement related to the DLC A Walk in the Park, as been acquired by only 7,3% of the owners. (07/13/2018)
Sixth : If you have an idea for a build, don't hesitate to ask what the community think of it. We could help you make it even better !
That's it. Be careful out there !
