If you played Halo 3 ODST, their is a cut scene where biofoam is used on a soldier. The soldier got hit in the chest by a gravity hammer that was welded by a brute. The impact of the gravity hammer caused one of the soldiers' lungs to collapse.
All described is the same scene. A brute chieftain came at the ODST squad and attacked Romeo, the squad sniper, with the blade side of the hammer. Romeo blocked it with his sniper rifle, but the blade was shaped and long enough to pierce his chest and lung. The rifle got bent in half and was thrown away. And that rifle is one of the clues the Rookie finds as he tries to catch up.
One of these days, Kip, we're going to drag you kicking and screaming into an ARMA 3 game, and introduce you into this world of pure jank and awesomeness.
14:30 It was actually planned for Halo 2, the Alpha Digsite got it into CE on their showcase map because it was so early in development that it was built on an engine closer to CE's.. The actual showcase, not the mission that's on the map. EDIT: It has also been canonized, much like practically everything else from the Digsites, the Troop Hog from CE is now the M914 Recovery Vehicle so it's no longer a troop transport but instead a Warthog that extracts knocked out or destroyed Warthogs.
3:14 is the point where Kip paused. 6:50 is when he unpaused. Kip was explaining things for 4 minutes! I'm not trying to be a jerk to Kip or anything cuz I like your content but the fact that you got through a minute and a half of Rubix's video and explained "progression in experience" for 4 minutes was stunning to me. Just wanted to point that out.
