Shadow Warrior

Hidden references to the original game

• Multiple secret areas in the game transition seamlessly into environments that look rendered by the Build engine of the original game. There is an example in the screenshots section.

• Each chapter except for the last one contains a pixelated anime girl bathing, the same way they are rendered in the original game. There is an audio clue to locate them as you hear them sing when you get near.

References to other games

Multiple game arcade machines can be found in the levels. They are not playable, but show the games Hard Reset, Hotline Miami and Serious Sam. The first was also made by the developer. The other two were also published by Devolver Digital. When you activate them, a music track from the game starts playing. There are posters of those games as well at various locations and an arcade machine of the original Shadow Warrior.

Viscera Cleanup Detail: Shadow Warrior

The digital version of the game comes with Viscera Cleanup Detail: Shadow Warrior, a free mini-game spun off from Viscera Cleanup Detail where the player needs to clean up rooms of one of the main game's opening levels. The mini-game is a separate application developed by RuneStorm and it uses a separate engine: UnrealEngine3.
