It's easy to forget how bad this game was. The level design went to absolute shit. Almost every level was a hallway. 343 forced ammo scarcity so half your time with the game would be spent scavenging for ammo. Most of my deaths during it came from running out of ammo. The covenant were nerfed into being mindless goons who all behave almost the exact same. The only real threat towards you are the forerunner knights who obnoxiously teleport around. I remember rage quiting this game. It was such a downgrade from 3. The only redeeming element was Cortana's new model.
