A special dive mode where you start out with nothing but your basic melee and have to acquire weapons and gear during the run would be neat. Equipment drops more frequently and enemies gain defense as you progress, making old, weaker weapons obsolete and forcing you to frequently replace parts of your build. Each time equipment drops, you get to choose one of three random options to take with you for the rest of the run. Part of the fun is figuring out how to decide what weapons are good or bad on the fly as well as getting to experiment with a wide range of builds. Players don't get to keep any of the weapons that drop when they finish the run, but they are rewarded with Carbon and EXP.
#Special mode where you start from nothing

i like this, its pretty much a mode completetly dedicated towards the rougelite aspects of the game
