The way you guys worked to solve being sandwiched between Buff-Riku´s with the check point was really great. One of the best Cursed Halo videos for sure.
5:14 Oh it's the Hoghog! Its counterpart is the Wartwart, which while I believe it's in the mod isn't accessible. You guys missed the custom cutscenes in the Keyes mission! Come on, both of those are amazing.
That's something I felt was missing in Halo 3 and onwards. I missed the large puddles of blood that oozes out of your foes (especially with the shotgun)
So Sophia (the tank at 5:35) is a Metal Attacker from the Blaster Master series it's a Metroidvania series were you take control of a tank for most of the game, but you do have to exit the tank for certain stuff the Blaster Master Zero trilogy is on Steam too
