About this game

Description

Supplied by the Steam store

The Supporter Upgrade for Murders & Mistresses. This is a completely optional DLC for Murders & Mistresses and the base game is required for the upgrade to function.

Whether you're an UndergradSteve superfan, want tonnes of additional goodies from the jump, or just loved your first journey through Murders & Mistresses and want a peek behind the curtain, the Supporter Upgrade has plenty of content for you to enjoy.

The Supporter Upgrade contains the following benefits:

Unlock Scene Gallery

You won't be able to unlock all the sex scenes in Murders & Mistresses in just one playthrough, if you're curious about what you missed but aren't quite ready to jump back into the game, the Supporter Upgrade allows you to unlock all scenes in the Scene Gallery to view at any time.

Extras Section

The Supporter Upgrade Unlocks all content in the "Extras" section of the main menu. Where you'll be able to find...

Behind the scenes videos with UndergradSteve talking about the making of Murders & Mistresses.

Developer Commentary created by UndergradSteve in a "Let's Play" style talking about every scene in the game in detail.

3 fully rendered non-canon sex scenes that do not feature in the base game.

Spoilers & Solutions

Guides to tell you the true solution to each detective case, as well as how to romance each love interest, earn every achievement, and achieve all the different endings.

Custom Wallpapers

A large selection of 4k wallpapers ranging from sexy to stylish to spice up your desktop background.

Unmade Scripts

Peek into the mind of UndergradSteve through six scripts, finished and unfinished, that didn't quite make it into the game!
