The Hand Sight is an Optics attachment that was added in the 4.15.0 update. Originally intended as a joke attachment, the Hand Sight is one of a selection of iron sights in the game. It provides an unusual sight picture formed by an "OK hand" emoji as the rear aperture and a "thumbs up" emoji for the front post. While obstructive, it has its purpose.
Welcome to 2020! There may not seem like there's much to do, but one of the pieces of information that languishes is the weapon pages. Oftentimes, the advanced information for each weapon may change in an update, and this can pass underneath the radar. Investigate weapons, ensure the information for the weapon is up to date, then move to the next weapon. There are a lot of weapons in Phantom Forces, but if you work with other editors, you can get the weapons up to date quickly and efficiently.
As always, if you dont feel like tackling a larger project, there is always housekeeping that needs to be done!
