Enemy movement system has been reworked to make any future adjustments easier for me to manage.

Interceptor fighter drones have been reimplemented as a potential wave end unlock along with a few upgrades such as hull integrity, fire rate, damage  and max amount in flight at a time.

Enemy spawn zones have been moved around and the respawn functionality for any that flyby has been tidied up.

Audio management has been reworked with various sound effects adjusted or replaced.

Enemy stats have had some balancing tweaks including difficulty scaling.

Temporarily reduced enemy model variety while reworking  their movement. Will increase variety again once new models are ready to go.

A few more changes preparing for the implementation of new functionality that will be added soon.

Added reload indicator and ammo counters.

A few minor UI change, such as resizing menu items, adjusting textures and moving the recharge indicators for missile barrage and emp wave weapons..
