how can i do that?

*sigh* It's always like this. Nobody understands

m8 pls speak normal xD

There is a free cam mode still left in the game. Activated by setting byte at:
AvP_DX11.exe +0x666534 to 1
then you can enable the used of Custom FOV by setting:
AvP_DX11.exe +0x666536 to 1
and specify it as a float value at:
0x9CFD74

AvP_DX11.exe +0x666535 is responsible for Fixed Camera (requires FreeCam to be set to 0).

wtf how xD

Out of body experience
