This update added new content, including new traps and weapons. The game also changed the viewing perspective to top-down, and content was redesigned to accommodate this (for example, ceiling traps are now wall traps). Also, split-screen multiplayer has been replaced with a shared screen. In VR, this is combined: you build in giant mode, but the character follows your movements in battle mode.
Here's the list of new features and changes:
NEW Hammer trap
NEW Push trap
NEW Energy Barrier (prevents projectiles from entering or exiting from the area)
NEW Swing Axe trap
NEW Mjolnir weapon
The biome is now procedurally generated with obstacles
New building system: Walls are now limited, and you receive a certain amount after each wave. Building any trap requires a resource. Resources are distributed randomly across the walls. For example, to build a mechanical trap, you need a gear in an adjacent cell.
Returned back rogue-like upgrades choices after each wave
VR: a 3D panel with traps has been added for more intuitive construction (pick up and place with your hand)
Improved visual effects for injuries—blood now flows from the cut site of creatures.
Improved trap impact effects.
Bullets now reflect off obstacles
Time slowdown and speedup (0.25x, 0.5x, 1x, 2x)
and more other improvements and bug fixes.
