I'm still astounded at how many they have available! One of the best elements of exploration is hunting down items to experiment with and potentially turn into something hilariously brutal. So a thread dedicated to us all posting our favourites--and not to mention to help people find them all--should be more than appropriate. 
 
Some of my favourites come adding the guitar+amplifier turning into a Power Guitar. It's not too effective but still a brilliant crowd clearer and really cool to use. The electric rake brought from Case Zero, made with a battery+leaf rake is as brilliant as ever, too.  The MMA gloves+nails is potentially my favourite, thus far I'd say. The Rocket Launcher made from a lead pipe+rocket firework is satisfying if not a little cumbersome because the blast radius very easily being hurled back at Chuck.

Lightsaber: gem + torch. The awesomeness is self-explanatory I hope.

The Telsa Ball is pretty amazing to throw in to crowds. Watching all that PP pop up.

" The claw gloves (bowie knife + boxing gloves) are insanely overpowered. Most of the psychopaths can be taken out with just a few hits. "
