It was pretty good shadow being drivable, phantom can be destroyed and the new weapons... Specially the smg was pretty fun to use!
However in some parts are weird?
The new encounters surprised me and definitly felt fair for maybe except sacred icon and quarantine zone (cuz the flood sucks to fight in this game)
But some encounters were weird, like at the boss fight of the heretic leader
He got killed by the flood before i could even touch him LOL
And the scarab fight on the level New mombasa uncut the enemies just stare at the sky for some reason? it was weird but pretty funny so

Yeah it is pretty good, except for sacred icon and quarantine zone
Hell even the final part of gravemind was awesome, now is longer and you have to fight more enemies on the arena!

Cool mod, cool new encounters and cool new weapons i hope to see this finished and get a rebalanced port by some other dude cuz that would be more enjoyable lmao

(also me love the new brute shot, is extremely useful now especially with the melee damage)
