Tentative Changes

Some changes have yet to make it into this build, either due to known issues or because they are simply not finished yet. I am including them here for full transparency.

  • New guardian, Revenant (found in The Abyss)

    • Excluded due to an issue with the turret targetting system that requires a slight refactor to support dynamic (moving) turrets. (you can test this yourself via "/spawn unit_revenant")

  • New guardian, Synthara (found in The Abyss)

    • Excluded due to an issue with interactions between this guardian and the new status affliction system, mainly Stun. (you can test this yourself via "/spawn unit_synthara")

  • 8 new quests to The Abyss

    • Excluded due to the above guardians being excluded. Quests heavily tie in with guardian fights, so without them these quests cannot be completed.

  • New gamemode, Creative

    • Simply not finished yet. I have not had time to get this off the back-burner.

  • New player progression system, Construct Shell

    • Partically completed, ultimately being excluded for the live release.

  • Upgrade tiers for all buildings in the game

    • Again not finished, have not had time yet.

  • 6 new achievements to the game

    • Excluded until the live release

  • New engineering mod, Re-Target. (after hitting a unit, orients towards the next closest one - only useful if bullet has piercing)

    • Not finished

Patch Notes

The following is a list of changes pushed to the experimental branch. While changes are usually tested beforehand, please note that some may require further testing to validate.

NEW CONTENT:

  • Added new "Discovery" and "Knowledgebase" system to help new & existing players understand game mechanics. Only configured up to research at the moment.

  • Added new crafting building, Status Chamber (spawns units nearby while crafting)

  • Added new crafting building, Compressor

  • Added new turret, Lancer (fires exploding projectiles)

  • Added new turret, Tesla (fires bolts of lightning, applying EMP status effect)

  • Added new unit, Healer (heals nearby units being damaged)

  • Added new unit, Shielder (deploys a shield which reflects bullets)

  • Added new drone, Builder Drone (places ghost buildings from blueprints or shift-click)

  • Added new drone, Fixer Drone (targets damaged buildings and heals them back to full health)

  • Added enemy outposts that can spawn throughout the world (not found in ALTAR)

  • Added enemy formations (will be used by RTS mechanics in the future)

  • Added 5 upgrade tiers for Fixer Port

  • Added 4 upgrade tiers for Lancer

ENGINEERING:

  • Added new engineering mod, Rapidheal (fixer drones heal considerably faster)

  • Added new engineering mod, Overheal (fixer drones can heal up to 10% over a buildings maximum health, works with rapidheal and areaheal mods)

  • Added new engineering mod, Areaheal (fixer drones healing trickles onto nearby buildings)

  • Added new engineering mod, Galvanized Rounds (inflicts the "Stun" status affliction)

GAMEPLAY:

  • Reverted dynamic heat system back to level-based heat system, making it easier to fine tune heat levels & understand the difficulty increase of each heat level

  • Changed how Armor works; now only breaks if hit by an explosion. Will be listening for feedback on this and making adjustments to the mechanic.

  • Changed how Shields work; now only breaks if hit by an EMP

  • Bullets now visually reflect off armor & shields

  • Updated range preview visuals using a new analytic shader to scale nicely at varying sizes

  • Enabled builder ports on the hub

OTHER CHANGES:

  • Removed all resource techs from the game; all resources are now unlocked by default.

  • Increased the maximum UI scale setting from 1.2x to 1.5x (note maxing this out may cause UI overlapping)

  • Increased the maximum bloom value setting from 1x to 2x (note maxing this out may cause flickering)

  • Changed default value for "Always Show Power Connections" and "Always Show Power Coverage" to enabled

  • Updated menu credits & re-enabled credits button

QUALITY OF LIFE:

  • Added a copy/cut/paste tool; activated via ctrl+c, ctrl+v, and ctrl+x shortcuts

  • Added a new recipe tooltip to display recipe details

  • Increased the text size for quests on the ALTAR OS interface

  • Updated resource slot tooltip to still display when the slot is empty but has a filter

  • Added the ability to traverse research trees with the movement keybind

BUG FIXES:

  • Fixed multiple UI components not being affected by UI scaling

  • Fixed incorrect description on empty tile design

  • Fixed turret's and other entity trackers sometimes missing nearby targets based on proximity to the edge of a tracked chunk

PERFORMANCE IMPROVEMENTS:

  • Various improvements to the entity tracking system on-top of the core tech improvements below

  • Various improvements to the drone dispatching system, which should make large amounts of drones less taxing on lower-end hardware

CORE TECH:

  • Refactored parts of the backend entity tracking system used by Turret's and Unit's to reduce GC and improve the time complexity of this system from O(n2) to O(n) - this should yield tremendous performance improvements on lower-mid end hardware.

  • Added ID context and a context transitioning utility to support Outposts & Blueprints (copy/paste), allowing global snapshots to be transitioned to a local context and then back to a global context

  • Added a new centralized achievement tracker for progressive/challenge achievements

  • Added a new effect mask for entity models that auto-bakes based on the provided sprite layers

  • Added a new formation tracker & "leader" status, supporting the ability for formations and the new follower unit state

  • Updated quest manager to allow optional objectives that are not required to finish the quest

  • Range stats are now uniformly authored in tiles, enforced via a new TileRange struct for all range accessors

  • Centralized range preview logic into one handler (was split across DefaultTool/EntityBuildTool)

  • Added the ability to lose regions by adding a "CanLoseRegion" flag on the data definition. This enables HUB vulnerability. Used for a new hidden region.
