Marine Corpses

General visual/creepiness improvements...
  Replaced the "2D billboard" style corpses with 3D models and textured them with gore.
  I posed the marines individually  and positioned them in the trees around the Jungle.
  I added a swarm of flies animation and a 3D "flies" sound effect for each one.
  Corpses drop to the ground with a sound effect as you cut them down from the trees.
  Improved the grass-textures and terrain-mesh around the edges of the map.
  Added muzzle-flash for tank cannon.

Planned future updates will hopefully include:
  Parabolic shooting (curved bullet path) using particle generator.
  Improved RADAR mechanism with near/far range placement.
  Settings menu (to lighten the CPU/GPU performance load).
  Animated waterfall, stream and sounds.
  Intensifying enemy waves/rounds.
  Player starts with 5 lives.
  Cloaked Predator with Shoulder-cannon (find/kill for bonus Power-up).
  Cannon Power-up improves player shoot-rate.
  RADAR Power-up locates enemies, marines and temple.
  Extra life Power-up grants 1UP Extra life. 
*Power-ups (except extra lives) are lost when player dies.
  Game over when all lives lost.
