23 years later and Halo: CE speedrunning is about to change forever with newly-discovered glitches that add playable Flood and a flyable Pelican

Halo: Combat Evolved came out over two decades ago, but speedrunning events for the classic shooter are about to change forever thanks to newly-discovered glitches that let you play as the Flood (Halo's version of a zombie-parasite-headcrab thing.)

Former Microsoft software engineer and Halo speedrunner who goes by Mr Monopoli has recently discovered a series of glitches that open up brand new routes in Combat Evolved.

"You can fully control it and even climb 90+ degree walls and even ceilings!" That added verticality is what I imagine will make certain levels beatable within minutes, as long as it doesn't take too long to actually trigger the Flood glitch.

Mr Monopoli also recently discovered how to play as Elites in Halo: Combat Evolved's campaign without glitches, a year after discovering a very similar glitch in Halo 2. "Here it is being performed on the OG Xbox!"

"We're just getting started with all the cool new stuff this is going to unlock," he also tweeted this week. "I became the first person to fly a pelican on Halo 1 without mods today." The video below then shows Master Chief kind of hovering in an aircraft vehicle called the Pelican, which doesn't seem
