Renting

This feature has been added to the weapons menu tab in Post Vacation Blues update.

Renting allows players to "rent" as in play with a weapon usually bought with real life money; in exchange for watching a video(advertisement).

This eliminates the "unfair" advantage of free players not being able to use those weapons. But the rent is only valid for 24hours. So, technically only those who bought the weapons will still possess them in true sense.
