The "Until Dawn" release for PC has a big issue with a missing crosshair — here's how to fix it.
The PS4 version of Until Dawn features a nice crosshair, that makes Quick Time Events (QTE) involving aiming with a gun easy to complete. However, in the PC version the crosshair is missing, turning the weapon QTE into something impossible.
Crosshair Solution
There is a universal solution, however — by using a crosshair overlay, which luckily is available as a free, opem-source download by developer Lacy Morrow called "Crossover".

One could hope that the developers would solve the issue in Until Dawn as well, but I'm not holding my breath.
