There is now a system in place which will reduce knockback that Enemies receive as each wave progresses. This only starts taking effect a while after overtime starts to prevent stalemates where the Enemies cannot reach you but you cannot kill the Enemies.
Enemies
Swarm Lord - Movement speed increased by +50%
Swarm Queen - Movement speed increased by +50%
Upgrades
Ion Focus - Ion-Cannon cooldown reduction increased to 65%, from 60%. Structure damage reduction reduced to -30%, from -35%.
User Interface
XR3-Photon-Refractor - Capsule descriptions changed to be slightly shorter.
Bug Fixes
There is now a failsafe in the case that there are no enemies remaining and the wave will not end.
Fixed an issue where in the end game screen, invalid structures could sometimes appear.
Transporter Capsule - You can no longer select invalid tiles to teleport structures to.
