You'll have to craft a lot during your time in Voidtrain, but you wont have access to a lot early on. This is due to the multi-phase research tree, which requires you to gather lots of materials to unlock new buildings and other useful features. In our Voidtrain Research Guide, we'll go over how research works, and each phase you must unlock along the way.

If you're after more information on the train itself, we have you covered — many of the research unlocks will make your train even better. We also have guides for the helpful Rofleemos, and how to get the most out of your guns.

Voidtrain Research Guide

Research is a vital part of your journey in Voidtrain, and is available early on. Once you're acclimatized to your new train, you'll be asked to create a Research Table. Crafted via 2 Scrap Metal and 2 Wood, the Research Table is where you'll view your currently available research and the materials you need. Completing research is as simple as having the required materials on hand, then selecting the research in research table. While it does take a few seconds to complete each research topic, you don't need to use any fuel.

The entire research tree is split into phases. Completing all research from one phase will let you move onto the next, which continues until you've completed everything. Sometimes, one piece of research will require a crafted item that must also be unlocked via research in the same tree. Outside of stat upgrades, you still need to make the actual items as well once research is completed — this generally requires the same materials used to complete the research.
