With the upgrade menu getting fuller with upgrades, and the "circle menu" as I like to call it a good looking style of upgrade menu, I drew up an style that will still be "circle-y". (It's pretty much a branching radial menu).
Lovely Picture made in MS Paint :D \/ (lower quality due to broken drawing tablet T-T)
(pretty great drawing with mouse I know)
It's mainly just a base concept that could fit more and categorize the upgrades by weapons, body mods, etc. In random upgrades a random category could be chosen and a random upgrade within that category. (Just a thought.)
Colors are there just for pretty factor, but it can be any color, because it's Doborog's game :P
I kinda just thought it up because circlez are a nice feng shui to the game.
(love you Doborog, you're my senpai)
