Gameplay
- Created a new objective-system that displays major and minor objectives (and their progress) on the HUD

HUD
- Redesigned entire HUD for a more realistic look and greater practicality
- Reticles now fade and change size to reduce on-screen clutter

- Reticles are now shown for missiles and mines
- Created a new radar-ball that shows the relative location of targets more clearly (can be zoomed in/out via CTRL+mouse wheel)
- Reticles are now rendered using the custom depth buffer

- Radio-icons are now colorized based on friendly/hostile origin
- Opponents of different types are now displayed with different reticle-shapes
- Created a new instrument-system that allows for each instrument to operate independently (significantly increases overall cockpit performance)

- Distance and relative motion to target are now displayed on the target-panel in a single readout



Graphics
- Tracers are now rendered using a new technique that takes into account both absolute and relative movement (much more realistic appearance)
- Projectile-impact flashes and light-beacons are now rendered using a sphere instead of a 2D-billboard (improves impact visibility)
- Lasers are now rendered using a 3D-mesh instead of a particle-system



Scenery
- Rearranged asteroids and debris in all missions (very tedious)
- Created a new debris-system that allows for larger moveable fragments and raining debris (seen in some missions like Firefight)
- Created icy asteroids and debris for "cold" levels
- Created destructible, glowing embers for "fiery" levels



UI
- Added live scenery behind main-menu (dropships and fighters attack each other)

- Hardware cursor is no longer used (blue/flashy cursor now used in all modes)
- Stats in various menus are now colorized to indicate "good" or "bad" numbers

Input
- Modifier keys can now be used when creating key-mappings (ctrl, alt, shift, etc.)

Audio
- Increased radius of debris-explosion sounds
- Master volume is now limited to a minimum of 5%
- Added new "super laser" muzzle-sound (more intimidating)



Bugs
- Fixed issue with game-over menu not displaying in rare cases (spectator-camera would become misaligned if target was destroyed)
- Current resolution is now correctly shown in the Graphics menu
- Fixed null-spawn warning that occurred when missiles were fired
- Fixed some preset resolution-strings with incorrect characters
- Eliminated invalid-object-type warning
- Fixed issue with laser-beams becoming misaligned with ship
