Whoa, I like this Hi Res version! Now you can see the details!

Lets see, we have:

Plasma Pistol/Rifle
Needler (Green parts on a purple weapon? And what's that mark on the bottom?)
Our first Hi-Res shot of the Plasma Grenade, PLUS a Plasma Explosion (Looks sweet!)
A "poop" shadow (Read the Weekly Updates)
Debris (Destroyable Surroundings?) (See ledge)
A SNIPER RIFLE!
Bullet Cartridges (See Blue Spartan on the right of the ledge)

And last but not least:

Realistic Death (note how the leg of the most right Red Spartan is in a weird angle, like he's spraining his ankle or something...)
