It’s a pretty rare find, but the combo of centipede and an electroshock unit works amazingly well. The shock the cbm provides is similar to the tazer, and with the number of hits centipede provides can stunlock a hulk without the actual stunned status. Still, the main flaw is the lack of compatible weapons for centipede.
Also, once more z-level buildings have been built, it could be fun to try scorpion and push zombies off ledges.
