Hidden Debug Menu#

A hidden leftover developer debug menu can be enabled by changing the following hex value inside prototypeenginef.dll in a suitable hex editor:

The debug menu can be activated from the main menu which allows the player to enter a variety of test levels.

In-game Behavior#

Activating the menu in-game by pressing the tilde key (~) while in the pause menu presents a different list of options.

Unused Powers#

Chameleonic#

The Chameleonic power would've presumably made Alex invisible to the military and infected forces. One image and a few strings related to this power can be found in the game files:

effectChameleonicSkin

ChameleonicSkin
Prototype Chameleonic Pass
Prototype Chameleonic Warping Factor
Prototype Chameleonic Warping Offset Scale
Prototype Chameleonic Blur Factor
Prototype Chameleonic Alex Colour
Prototype Chameleonic Infeced Colour
Prototype Chameleonic Colour Mix
proto_lit_chameleon

Spines#

Watch on YouTubeThe Spines are a scrapped defensive power with no icon, transformation animations, or sounds. They deal 10 reflect damage to attackers.

This function seems to be unfinished because it renders the attacker invincible when their health gets too low.

Unused Maps#

There are a bunch of test maps found in the files that can be loaded with the debug menu or through launch options. Add a new line with Level= followed by the map's name (eg. “Level=manhattanTest”).

• manhattanTest: Starts the game with all upgrades unlocked, no missions, and no infected or military.
• Millitary_Test: Every space that can hold a base is held by the military.
• Infected_Test: Similar to Military_Test, except godmode is enabled and the enemies at the hive you spawn in front of won't target you.
• empty_e3: Similar to manhattanTest, but with no AI, vehicles or other characters at all. Just you in an empty city.

The maps below were added in the September 29th, 2025, Steam update:

• Note: All of these spawn you in a Manhattan similar to the one in manhattanTest except c18m01, c50m03, and manhattanTest_mini, which are unique. These maps aren't unique to this Steam update, they also exist on the PSN version of the game.
• MissionPackage_Test: Seems to be identical to manhattanTest.
• NIS_Test: NIS means Non-Interactive Scene which are the in-engine cutscenes. Loading this map plays 8 of them. Every scene played loads the version of Manhattan used by the mission.
  • Scene 1 (e01m01): Alex wakes up in a morgue.
  • Scenes 2, 3, 4 (e01m02): Alex passes out and consumes for the first time, Alex learns where Dana is, Alex saves Dana.
  • Scene 5 (e02m01): Alex enters his apartment and gets blown out of it.
  • Scene 6 (e02m02): Alex learns where Greene is.
  • Scene 7 (e04m04): Cross injects Alex with the syringe.
  • Scene 8 (e04m05): Alex confesses to Dana all of the things he's done. Loads a Manhattan with 4 zones: 2 infected zones near where Dana was held by Greene, 1 infected zone at the north edge of Manhattan, and 1 military zone where the fortress is.
• These 10 prop test maps below feature various props, laid throughout Times Square. No NPCs spawn except in PropTest_10.
  • PropTest_1: Playground and construction props. All weapons with infinite ammo. Signs and rooftop props.
  • PropTest_2: Gibs. Pieces of bases and hives. Two large towers and inactive base turrets. A bunch of lights.

• Specialist: Internal name of Captain Cross. Spawns you below the map and seems to be identical to manhattanTest otherwise.

• c50m03: A tiny gray map that contains one tower with low walls around it. Alex cannot Airdash or Glide in this map. There is no ambient sound, no objects, no NPCs. Alex can fall out of this map into the void.

• manhattanTest_mini: Manhattan with only Times Square. The rest of the map still "exists", with pedestrians and vehicles constantly spawning and falling through the map. Alex's out of bounds protection is still active, letting him traverse through the rest of Manhattan.

• test_cwinder: Spawns you near Times Square next to an infected zone and 3 blue mission markers on a rooftop, each larger in size. There's a yellow mission marker on the opposite building. They don't seem to do anything or respond when touched. There are no NPCs in this map. cwinder refers to programmer Chris Winder.
