Venom-X Button Box Solver
The box on the wall by the 'Ops Center' stairs opens with three to six coloured buttons inside. Enter the colours you see and the round you are on to get the one button to interact with.
Select the number of buttons and your current round, then tap the color matching each button in-game (top to bottom). Every box except the 3-button one changes with the round, so it has to be right.
The game tracks one of its own variables incorrectly (found after looking at the code), so the solver can occasionally tell you the wrong button. That's just a bug in the game, and not something I can build around. Sorry.
