Brotato's Abyssal Terrors is bargain content for an already permanently bargained game. The new bros ask a lot more technicality out of your build-approach than earlier iterations, but each one has fantastic gimmicks once you've gotten your bearings on them. Shout-out to Buccaneer to being the absolute chad king of doing 100,000+ total damage on each of his weapons once you've gotten multiple obliterators and grenade launchers on him along with auto-looting.
I have the impression that the new map will undoubtedly see possible nerfs in the future due to the intensity of it compared to Crazh Zone (Vanilla), but I also feel like the general concern that a lot of vets of Brotato will need to face is that nearly all the enemies and elites featured in it are brand new, and thus require newer expectations. I didn't start running Abyss until I finished D5'ing all the new characters, and now that I've started my D5 deep dive into the underwater-themed nightmare, I can tell you: It's beatable, but it does require a lot of studying of your new-found opponents. I've gotten so used to Crash Zone that jumping into Abyss felt like I was playing Brotato for the first time, which is an excellent feeling. But now that I've learned which enemies get priority slaughter, the heat is officially on, and it feels gloriously fun to now face the opportunity to test everything I've learned from vanilla on every character's Danger 5 path.
Added Local Co-op to this expansion's release is the cherry on top, and I'll add that to this review by saying that this is the best new addition to the game, and getting the opportunity to now experiment with wild combinations with friends is crack.
If you already own Brotato, then you're buying this. No buts. Do it.
