📋 About This Mod
This mod adds craftable MK2 and MK3 variants of the Prawn Suit Drill Arm.Tear through large resource deposits in seconds and make late-game farmingfeel like a reward, not a chore.
Important note:
This is basically still the original Subnautica version under the hood, just tweaked to work with Below Zero.
Only did some rough testing so far, so yeah… stuff might break.
If you find bugs, report them, I’ll take a look.
Also, everything pinned in the original mod’s posts section still applies here.
Not gonna repost all that stuff again.
>>> Original: Prawn Drill Arm Upgrades
Prawn Drill Arm Upgrades
Prawn Drill Arm Upgrades expands the standard PRAWN Suit Drill Arm with two new upgrade tiers:
-
[]Prawn Drill Arm MK2 [/]
[]Prawn Drill Arm MK3
Both versions are designed to make resource drilling with the PRAWN Suit much more efficient and rewarding. Depending
on your configuration, they can drill faster and also provide increased resource yield from drillable deposits.
The original Drill Arm remains fully usable, while MK2 and MK3 act as proper upgrade paths for players who want to
improve their PRAWN Suit in the later stages of the game.

preferred playstyle.

mining tool.
