Halo 3 - Installation 00 | Wow, This Custom Campaign Mission Was... Amazing

Installation 00 might be one of the most impressive Halo 3 mods I've played so far. This isn't just a custom map or a short encounter. It feels like an actual campaign mission, complete with large-scale battles, objectives, vehicle sections, and plenty of Covenant and Flood to fight through. I went into this expecting another fun Halo mod. I wasn't expecting something that felt this complete. There were moments where I genuinely had to remind myself that I was playing community-made content rather than something pulled from an official Halo campaign. Wow. This was amazing. Halo 3 custom campaign mod gameplay with no commentary and light editing.
