Update Preview[]

New Features[]

Three New Enemies[]

  • BET-C - The Battle M.U.L.E

Deep Rock Galactic didn’t invest much in the safety system of their BET-C series of combat M.U.L.E.’s. It only takes a few Xynarch Charge-Sucker parasites licking the robot’s circuits to turn them against the dwarves. In that situation, BET-C’s fast-tracking auto-turret and grenade launcher could become a major threat for any expedition. If you find an infected model, aim for the attached organisms and, once they are eradicated, carefully hammer BET-C until it turns into a trustworthy companion for the rest of the mission.

  • Q’Ronar Shellback

The Q'ronar Shellback is a deadly creature that you might bump into in the Radioactive and Salty regions of Hoxxes. Their tough shells and fast movement speed make them quite hard to kill - try to dodge its rolling attack and kill the Shellback when it stops to spray poison venom at you.

  • Naedocyte Shocker

The Naedocyte Shocker is a strange alien flying jellyfish-like creature. They often appear in large swarms and is preferably dealt with before they get close enough to zap you with electrical shocks. So far they’ve been spotted in the regions of Dense Biozone and the Glacial Strata.

New Hazard Level: Lethal[]

By popular demand, we’ve added a LETHAL new difficulty setting only for the most masochistic and badass dwarves out there! We hope you have “fun”... :D

Difficulty 2.0[]

Enemy wave spawn logic has been tweaked, and multiple bugs have been fixed, allowing for a fairer challenge.

  • General Spawn Logic:

The general logic behind how we handle spawns has gotten a big overhaul - balancing waves is now a much more exact and controllable thing for us. This is actually the biggest of all changes we’ve done to the difficulty system, but also the hardest to explain in detail - maybe we’ll do a blog post on this in the future :-)

  • Mission Specific Enemy Types:

The Mission Generator now also pre-selects the specific mix of enemies players will encounter in a given mission. Instead of randomly selecting from every enemy type available in the game, players will now face themed swarms of enemies. This change won’t be particularly visible right now, but will serve to improve the overall feel and flow of the enemy swarms as we add more enemy types to the game.

The goal here is to make each mission feel a lot more unique, as well as making it more attractive for players to pursue a more strategic approach - if you have a rough idea of what awful things you might face down in the depths, you stand a better chance of going in as prepared as you can be.

  • Time: As a rule, lowering the time between spawning enemy waves means more enemies in general, which results in an overall higher difficulty. Knowing this, we’ve made a few changes to how we time waves:

Time elapsed before the first wave appears is based on Difficulty - so higher Difficulty means the first wave arrives faster. Subsequent waves will also spawn faster depending on difficulty level.

  • Speed: Attack speed, projectile speed, and movement speed of enemies are increased for the highest difficulties.
  • Environmental Hazards: You now take more damage from environmental dangers on higher difficulties.
  • You Get The Waves You Deserve: Multiple waves are now allowed to spawn at the same time and do not cancel each other out.
    • Example 1: Digging two eggs out in Egg hunt will generate two small waves instead of only one.
    • Example 2: You can not cancel a wave in progress by calling in the Drop Pod

Weapon Mastery[]

A Weapon Mastery Bar has been added to all gear - as you unlock mods for a given piece of gear, your Mastery with it increases. At certain levels of Mastery, you’ll gain free bonuses. For now the bonuses are restricted to Skins, and only for the primary and secondary weapon slots. Each weapon has three unlockable skins to get.

The majority of our time with this has been spent on getting the system up and running, but we definitely intend to expand on the Skins System as we move a bit further ahead - you can expect other ways than just through the weapon masteries to earn skins in the future.

Other Notes[]

UI Improvements:

  • New Enemy Health Bar
    We’ve completely revamped the way we put health bars on enemies. Now it will show when the player is aiming at an enemy and it will do it on top of that enemy (instead of in the center of the screen). Additionally, it displays the damage applied to the enemy with every shot.
  • New Mission Readout Bar
    The Mission Readout Bar visible on the Space Rig has been updated with more information about the mission in progress, as well as gotten a graphical overhaul.
  • New Biome Content
    In The Salt Pits Region, you’ll now start seeing fragile Salt Platforms - stand on them, but be careful. They’re not tested for dwarf girth.
  • Prevent Late Join Duplication
    You want a diverse team? You don't like teams with three Engineers? The Host now has the option to select “PREVENT LATE JOIN DUPLICATION” from the Escape menu and Options menu. Selecting this option means players LATE JOINING your game will need to select a character class not currently in play.
    Please note: This option does NOT restrict character selection on the Space Rig - we leave that up to you guys to figure out among yourselves.
  • More Equipment Modifications
    The new Modification System has now been implemented for the traversal tools. That means more customization for the Power Drills, the Platform Gun, the Zipline Gun, and the Grappling Gun. Furthermore, your armor modding opportunities also got some tender, loving care...
