Some peeps poked me to download the beta so I did.
All in all it seems really solid with a couple exceptions. I'm still unfamiliar with things, but most weapons seem to be balanced really well with the exception of the hydra.
The bots are actually pretty fucking neat too when you crank the difficulty up to max. I like how they juke and strafe like an actual experienced player would. What I find neat about them is that I don't particularily feel cheated by them if I get gibbed by them, more like I just got juked and missed my aim.
That's a huge step up from how awful the AI was in Halo 5. It makes me wonder, if they can make AI that decent, could they introduce them into firefight or even custom games involving forge mode?
