can you use "freelook" in this

[FINE JEEZ]

i heard about something called freelook that you have to enable to be able to look up and down is it possible or is it only regarding doom 2?

[Chop Suey]

If you use the sourceport (engine) GZdoom or Zandronum you will be able to look up and down. I suggest you use GZdoom,because many sourceports (like zandronum) for example use a technique that only simulates looking up or down (it does some vertical letterbox thing because the engine doesn't support 3d floors). This results in weird warping effects.

I don't know if there's a way to keep vertical autoaim and allow freelook though. The shotgun is allot harder to use when you have to place your shots rather than just aim in their general direction.

Freelook was originally added in the Heretic source code, and I know Hexen has objects that are not infinitely tall, so any DOOM Source Port based upon code forked, then re-merged, should support full freelook.

The DoomsDay Engine is just such one engine (that was forked out from DOOM v1.2 and the Heretic and Hexen Source Ports, then back to support DOOM v1.9).

It is available here:
