[1.12.5] TechTrees: QUARTIX 3.8, TETRIX 2.24 SIMPLEX 1.34 (2024)

The Tech Tree is divided into four branches, each with four strands.

Each branch is nine tiers long. Four tiers before the R&D Building upgrade, three before the second.

Tier 1 - 5 science - size 0 tanks (0.675m)
Tier 2 - 15 Science - size 1 tanks (1.25m)
Tier 3 - 30Science - size 1.5 shorter tanks (1.875m)
Tier 4 - 60Science - size 1.5 longer tanks (1.875m)

R&D Upgrade Required
Tier 5 - 120 Science - size 2 shorter tanks (2.5m), Mk2 Systems
Tier 6 - 240 Science - size 2 longer tanks (2.5m)
Tier 7 - 480 Science - size 3 smaller tanks (3.75m), Mk3 systems

R&D Upgrade Required
Tier 8 - 960Science -size 3 longer tanks (3.75m)
Tier 9 - 1920 Science -size 4 rocket systemparts (5.0m)

LIMITED Modsupport included (not supporting the mods, just included a patch to balance in the tree)

ALSO SUPPORTED

• SNACKS! (Instead of Kerbalism)

Supported mods with part upgrades show additional 'upgrade' nodes requiring further science points to unlock. These will only appear when the supported mods are installed. Supported for upgrades: Kerbalism and KSPIE.

From 2.8 the Avionics Nose Cone is available at the Start node, and has a part upgrade to add the SAS functionality later in the tech tree. It also includes an experiment to assist in getting through to the first tier of experiments.

The Tech Tree is divided into five branches, each with two or three strands.

Each branch is nine tiers long. Each upgrade level of the R&D Building enables three strands. Each tier doubles the cost of nodes.

Notethat this is with icons prior to 2.14

All nodes are based on Stock, with three exceptions, and around half the parts have been moved for balance. Making History and Breaking Groundare supported. Additional mods have been supported over time.

It is possible to play non-crewed before crew (unmanned before manned).

The AngleCan SIMPLEXTechTree 1.29is divided into five branches, each with two strands.

If you want a lightly modded save, ReStockPlus on its own will ensure every node except the final crewed node (bottom right) will have parts within it. Kerbalism will fill this final node.
