` (the key above Tab) to toggle:Screenshot Mode
This will freeze all characters in the game, including the Xenomorph. Physicalised objects such as the tail and limbs on some of the Nostromo crew might occasionally spaz out, but it's very rare. It's not entirely stable and reckless use might cause a crash, though I've been using it largely without issue. It does freeze you, however, so you'll need to use the freecam to move about.
Activate the script first (click the box)Free Camera
Numpad * to enable, Numpad / to disable:
The tilt function of the freecam has the side-effect of hiding the game's particle effects when the freecam is enabled. Line up your shot, switch to your higher resolution, exit the menu and then use this key to freeze the game, restore the particles, and hide the HUD. You'll see what I mean. If you get depth of field issues then ensure the Post Processing override is active. You can set up any Post Processing after lining up and freezing your game. This goes for depth of field, bloom, saturation, lens dirt, barrel distortion, vignette and the like.
F4 to toggle (use F2 to toggle non-tilt freecam in emergencies - see above):FOV
Numpad 8/2 - Forward/back
Numpad 4/6 - Left/right
Numpad 9/7 - Up/down
Numpad 3/1 - Tilt
These are xyz coordinates which may not reflect your directions in game. Experiment.
F1 to toggle:Depth Of Field
Numpad +/- - Adjust FOV
Numpad 0 to toggle:Post Processing
U/J - DoF strength/blur radius
I/K - DoF focal length
O/L - DoF focal range
These are almost certainly not what these parameters actually do. No two DoF systems are quite the same and it's pure guesswork on my part, and there might well be additional values. DoF is quite unwieldy and looks worse at high resolutions due to how it scales. This is fairly common for DoF.
The toggle will disable all the game instructions I've found which alter the DoF values, including those of the motion detector and the main menu/options screen. Let me know if you discover others. Those systems will still work, though.
Numpad . to toggle:Remove HUD (thanks, K-putt)
Lets you adjust:
Set the last of these to 0 to greatly improve the game's image quality by removing the stylistic distortion of its pixels. This should allow for much more precise antialiasing.
F3 to toggle:Download
Q - brings up the radial menu which in turn disables the HUD. Doesn't work in all situations, unfortunately. This function is rendered largely obsolete by the Screenshot Mode.
This table is AOB-enabled and should work on all versions of the game. The only caveat is that the Post Processing code changed substantially after a recent build, so use the deprecated script (included) if using an older one.
