Gadget and wall sounds can now only be heard within about 10 floor tiles. Tik's detection alert still reaches you anywhere on the map.
Off-screen "!" markers now only appear within that same hearing range (gadget triggers, wall hits, gadgets taking damage or being destroyed, walls breaking, cracked walls collapsing).
Magrik now plays a warning sound while arming, and Detrix while its fuse burns, so you can tell they're about to go off even out of sight.
Magrik now makes a sound when it fires.
Slowed enemies and players now show a slow marker above their heads.
Slok now glows and hums while it is slowing enemies.
You can now open the Codex from the pause menu while playing.
Fixes
Fixed enemies walking around outside the outer walls to reach another entrance when their entrance was blocked.
Fixed Hargu attacking targets inside from beyond the entrance tunnel. Gadgets can no longer be placed on entrance tiles; you can place them starting from the tile in front.
