Mini - Master Chief Action Figure:

In Delta Halo, when you get to that "staircased" waterfall that you must climb up, then jump onto what appears to be a sniper rifle case, then a quick jump to land - as you turn that bend past that cave where the covenant snipers were - head into that cave - it is a dead end... Take a look at the floor - with a scoping weapon... A golden mini-Chief action fugure will be there. If you shoot it, it will also bleed.
