The riot system is making me lose some hair.
Nothing works. the upgrades don't reduce the chances.
They just want to riot.
They do reduce the chances but iirc it's adative (i.e. the game always progresses to a guaranteed riot to discourage subsidy farming) so the effect is not very noticable.
After you clear level 3, the stripper job keeps you guaranteed riot-free for a day, though.
How do we view scenes you already unlocked? is there any way
Nearly all scenes are repeatable. Just trigger the conditions that cause the scene again. The only non-repeatable scene is the epilogue scene, but it just re-uses an existing scene but with a wedding dress.
Use the give up skill in combat to instantl enter defeat scenes. Let your desires rise in combat for combat sex. If you want a specific enemy, use gauntlet mode on floor 5 or CCMod. Do (or fail) at jobs for the job scenes. Gallery is kind of unnecesary with how easily accessible all scenes are in freeplay mode.
