- Hold RMB to focus the cutter's laser, mining ~6X faster
- Bind Alt as a secondary jump key to boost forward
- Companions only need one ammo to use a weapon indefinitely, including grenades
- In the lodge, the safe in your room and some of the containers in the basement have infinite storage. Some containers in procedurally generated structures do too - but none as convenient as the lodge
- Cancel your ship boost (with S) to evade missiles without fully using up your boost, or spam boost-cancel in combat for the engine systems perk challenge
- With a precise click, you can land between multiple biomes and build an outpost with resources from all. I've got a triple, and suspect a quadruple is possible
- Setting up an outpost with some extractors and a large amount of storage, then spam-crafting items 99 at a time, is super-fast XP
- Cargo links work in real-time (every 3 minutes) rather than game time. For the trick above, you'll need to produce all ingredients in one outpost (e.g: Archimedes III for drill rigs, which are a rare component so give more XP than just adaptive frames/etc.) if you want to make full use of sleeping
- Venus, Charybdis IV, and Katydid III all have 1:100 ratios for sleeping (1 hour slept = 100 UT hours)
- Being over-encumbered still allows you to sprint (but not fast travel)
- Health drain from moving with full CO2 won't fully kill you
- The more over-encumbered you are, the faster O2 drains. Being very over-encumbered can even overcome personal atmosphere's O2 regen, allowing you to rapidly drain (by stepping forward) then regen (by briefly standing still) your O2 for the fitness challenge perk
- The fitness perk challenge actually requires filling CO2, not just draining O2, and the "Life Begets Life" achievement only counts flora, not organic materials from fauna
- The ship landing animation only plays if you're sitting in your cockpit
- The perk you get from a non-recipe magazine is determined by how many of that series you already found, not the magazine number
- Magazine perks persist through NG+, and magazines respawn
- You get all resources back when destructing outpost modules, or the entire outpost at once
- You can steal starborn ships if you get there before the starborn exit, or have that bug where enemy ships are empty
- You can instantly fully-scan gas/ice giants from space to get survey data (and Vlad buys survey data for the most money)
- Killing fauna and collecting minerals/flora counts as scanning
- For minerals you can scan the ground areas (where you can place extractors) and dropped item versions (even if taken from elsewhere), not just the mineable rock deposits
- After unlocking ship thrusters, use them by holding space and a direction
- Novablast disruptor and magsniper can be charged by holding left click
- You can access ship's cargo from the menu if within 250m
- You can place storage adjacent on all directions, like this: https://i.imgur.com/eqfiXvD.png
- Hold E to pick up a physics prop, then hold and release R to throw it - the longer you hold R, the further you throw
- Laser weapons can be used through windows/glass
Also a cheesy one to level: each hit with a silenced automatic weapon counts as a sneak attack as long as your not full detected, rapidly filling the challenge for sneak.
