Upgraded Vehicles greatly increases the benefits you gain from adding a new depth module to your small vehicles.
New Benefits to Upgrading your Depth Modules
When you install a new depth modules in your Seamoth or Prawn Suit, it will gain additional bonuses in the form of:
· More vehicle armor (reduced damage from impacts and creature attacks)
· Additional movement speed (go faster at no extra cost)
· Better engine efficiency (power cells last longer)
All this for free just from the depth upgrade module.
New Vehicle Upgrade Module: Speed Boost Module & Mk2, Mk3, & Mk4
· Kicks your small vehicle into high gear, adding extra speed to get you there and back faster.
· The added speed does come at the cost of reduced engine efficiency.
· The bonus speed added by the depth modules though comes free ;-)
· Craft it at your Vehicle Upgrade Console.
New Vehicle Upgrade Modules: Hull Reinforcement Module Mk2, Mk3, & Mk4
· Rather than waste precious upgrade slots of multiple armor modules, why not upgrade them instead?
· Now you can get the benefits of 2, 3,or even 4 armor modules in a single slot
· So that you don't feel obligated to craft multiple of these, hull reinforcement modules no longer stack with each other
· 3 new tiers of hull reinforcement modules are available to craft in the Modification Station
Altered Items
· All Hull Reinforcement Modules now grant your vehicle some damage reduction against all types of damage, even
creature attacks.
Finally, it's not totally useless!
Cross-Mod Bonus
· If you're also running More Seamoth Depth Modules mod, the Seamoth Mk4 and Mk5 depth modules will grant increasing bonuses over the Mk3.
User Configurable
· The extra bonus speed provided by depth modules is now configurable in the Mod Options menu in-game.
· You can leave the bonus speeds as is, slow them down a little, go faster, or even outright disable the extra speed
· Bonus speed settings to the Seamoth and Prawn Suit ca
