First Person Shooter Mode

Allows you to play the game in FPS mode.

Just tap T during a run to toggle it. (can also toggle options using the Mod Config Menu)
Press Up to attack, Left and Right to turn.
(You are able to press turn while holding attack)

In the bottom right corner of the screen, just above pill/card slot, you'll get a little map of the room and the enemies so you can know if there's something coming up behind you.


The Skill Levels are:
"I'm too young to die" Start with The Wafer, Old Bandage, Gimpy and Infamy.
"Hey, not too rough" Start with The Wafer and Old Bandage.
"Hurt me plenty" Default value, no effect.
"Ultra-Violence" Damage is 1 heart minimum even before womb.
"Nightmare!" Damage is 1 heart minimum even before womb, you have Curse of the Tower.

If Free rotate mode is enabled you can face and shoot 360 degrees, in this mode you can hold left or right attack to continuously turn and can hold Down at the same time to turn faster.
If it isn't enabled pressing turn will turn you 90 degrees and pressing down will turn you 180 degrees.

If you have REPENTOGON you can enable cursor locking, allowing you to play using the mouse rather than aiming with keyboard/joystick (though you can still use those)

If you want some music to go with it consider subscribing to the DOOM Soundtrack mod.

Comes with it's own HUD (if you have HUD API).
Thanks to Gummy for designing and spriting the 'Doom style' HUD and for making the cool new sprites for the room minimap.
You'll also be able to set which HUD is used by default for when FPS mode is enabled in the config menu.



Mods that render sprites might render stuff on top of this, I can't really control that without simply making this mod last in the load order, but if I do that then stuff like EID, reHUD and MiniMAPI won't be able to work.

Might run a bit slow sometimes if your PC isn't great, I mean it is essentially rendering the whole room twice over, on top of doing a bunch of extra calculations.
On my PC it's generally fine unless I'm in a big 2x2 room but it goes slow if I'm running OBS at the same time, which is why it gets a bit slow in the video.
