I don’t even know where to start with this. Prometheans are flawed in every aspect of the game. First of all, they’re not properly explained in the games. In Halo 4 they were Forerunner defense AI, but the knights were imprisoned humans? or were they digitized forerunners so they could not get infected by the flood? I don’t know and neither does 90% of the Halo community because the game didn’t bother to properly explain it. Same thing with this ‘‘new Covenant’’. As a result the Campaign of Halo 4 felt like a missed opportunity and the Campaign of Halo 5 felt borderline useless because the Prometheans were totally irrelevant to the narrative in that story.
As far as their design goes, they looked pretty good in Halo 4. The E3 2012 demo portrayed them like they should’ve been; powerful and mysterious with ancient but advanced sounding and looking weapons. In Halo 5 they look and sound like something you would find in a T rated fantasy game involving generic robots (yes, that comes close to H5 but that’s not a good thing). The Prometheans and their weapons in Halo 5 look and sound far worse than in Halo 4. Just take a look at these clips
And last but not least, they are TERRIBLE to fight in Halo 5. A Promethean soldier takes approximately 6 or 7 melee strikes before he’s killed, while he can kill you in 2 or sometimes even 1. You know you have horribly designed enemies when the best way to fight them is to peek and shoot from a distance. Prometheans do not allow hand to hand combat like Bungie’s Covenant (343’s Covenant have the same issue) which takes out a pillar of the Halo sandbox: Melee. They come in far too many numbers and the way they spawn is just lazy and stupid. Wouldn’t it be a lot cooler if we actually saw the metal parts slowly assemble instead of this purple cloud crap, it would give the player time to react while looking a lot more convincing itself. The way Prometheans are currently is far below Halo standards.
