as the title says.
simply have an item called Binoculars that uses a modified F10 FPS screenshot rendered inside the game in a nice gui (that I can create).
the idea is you can use this item see if shot is clear. it should have a flat 10 TU use.
by modified i mean there is also a sky as gradient blue that gets darker/lighter depending on darkness level using same sprite darkening mechanism.
it should work kinda like the stats screen you use and a new screen shows up with a rendered FPS view inside a gui. there is a vertical dashed line right in the centre showing possible aim shots.
