(I hope I'm not too late to join!)
Dressed in a steamlined, all-black stealth suit with a light tactical harness, Shinobi stepped out into the arena, locking a suppressor onto the barrel of his handgun before holstering it on his right thigh. His muzzle was covered by a gas mask, and a pair of compact, multivision goggles rested on his forehead. His combat knife was strapped securely onto his harness in front of his left shoulder, hilt-down so it could be drawn at a moment's notice. Also at the ready were several extra mags for his handgun, along with a small personal medkit and belt of smoke grenades. On the inside of his left forearm was a wrist-mounted computer. He brought up its holographic display and pressed a few buttons, causing his form to ripple briefly before disappearing, leaving only a faint, translucent silhouette where he stood. He made his way to the nearest hill and went prone, his active camo allowing him to fade perfectly into the grass as he crawled up to the top to get a better view of the battle.
