Make it Predators 4 Aliens 2 (and friends)! I think this is as complete a transform list as possible, but if you know any other mods then please comment. None of these mods are made by me, so if you like this collection then please go to the creators pages and thank them for their work!

Some external files are required, these can be found at the following links:

Alien Special Infected: http://www.gamemaps.com/details/2206

Predator (Unmasked) as Coach: http://www.gamemaps.com/details/4415

Predator as Nick: http://www.gamemaps.com/details/4137

Predator Survivor Images (in-game images): http://www.gamemaps.com/details/4492

: To install those files you need to extract them then right click on the .vpk file and open it with the Steam Addon Installer located in your "Steam > steamapps > common > Left 4 Dead 2 > bin" folder by selecting "Open With" and selecting the file addoninstaller.exe to open it with in Windows.

Note: You'll get a warning when using the Predator Survivor Images with the Survivor re-skins, ignore it as they worked fine together for me but if any issues then simply disable that one.
