Gladias9 has released a mod on Nexus mods which includes an FOV fix. You can obtain it here[www.nexusmods.com]. This will be easier to use than the method below. Should this not work in the future, you can still use the method below.

EDIT

As of the Season 2 update, .pak mods like the ones listed above will be flagged in game and you'll only be able to play solo. Unreal Engine Unlocker method can still be used to changed the FOV in multiplayer.

1. Download the Universal Unreal Engine 4 Unlocker v3.0.19[framedsc.github.io]



2. Extract the files

3. Start Aliens Fireteam and "Continue Game" from the menu

4. Run UuuClient.exe from the Universal Unreal Engine 4 Unlocker



5. Select the Alien Fireteam process and click inject the DLL:



6. The window will now change and look like below:



7. Tab back into the game, open the console using the tilde ` key. It's located above tab. If you have a different keyboard configuration, you can alter the key in the Configuration section in Uuu:



8. Change the fov by using the 'fov xxx' command. The number pad 0 key is also the pause game function for UUU. So after entering e.g. Fov 90, you'll need to press 0 again to unpause your game.



9. Please note, you have to enter the FOV command at the start of every mission as it resets back to default. You'll also have to do all of the above everytime you start Aliens Fireteam

Default



FOV 100
