About this game
Description
Supplied by the Steam store
Hey guys, Undergrad Steve here!
If you loved M&M and want more of it while also supporting us, this Supporter Upgrade is for you. It contains a ton of bonus content, all easily accessible from the in-game Extras menu.
Here's what's in it:
3 Bonus Sex Scenes with 9 New Animations
Crash Victoria's almost-wedding, seduce Nicole, and watch Frank and Olivia's steamy last hour leading up to their deaths.
Unlock All Sex Scenes Button
Unlock the entire "Memories" collection — every sex scene in the game — with one click. Optionally you can also only unlock non-open-marriage sex scenes.
13 Hours of Developer Commentary & Behind The Scenes Videos
Watch me (Undergrad Steve) talk through my process and design decisions, then play through the entire game start to finish, giving my thoughts on every scene I come across. The first commentary episode and the first behind-the-scenes video are both included in the base game's Extras menu, so you can check them out if you're unsure.
22 Wallpapers
22 stylish and sexy 4K wallpapers, featuring your favorite love interests.
7 Guides
Find out what really happened in each case, how the hostage negotiation works, how to romance each love interest, and how to earn every achievement in the game.
6 Deleted & Unfinished Scripts
6 of my screenplays, some cut from the game, others unfinished bonus scenes with my notes on why they were cut or not finished.
Thank you for supporting a small team making ambitious games.
— Steve
