I think it would be really cool if you could trigger a short animation, maybe 2-3 seconds where the predator removes their mask and drops it for the rest of the hunt. Could be tied to a dual button press, e.g L3 +R3 press and hold for a couple seconds to trigger it.
I think it would be very cool and thematic letting you have this option as often when one person is left alive I wish I could do this, also sometimes it would be interesting to just drop the mask and try to hunt without thermals.
You could even go a step further and make the predators dropped mask become a bonus objective icon for the fireteam, if retrieved awards Xp and Veritainium, but the predator could also use this to potentially set a trap
Thanks for reading my ideas
