I thought the same, before playing Zero Hour. That is some insane trash lmao You fight for like a second, then go through insane amount of mundane BS, super mario platforming, pushing switches, simply walking down the most boring looking corridors, etc.etc. It's so mind numbingly boring that I couldn't make myself complete it at least once. It's the 1st mission in the game that I didn't complete. Enemies are fine, a bit tanky that's all, but everything else is absolutely obnoxious. I've never been so bored playing a video game before.
