Hi.
I think that would be quite interesting and not so far from the original. AFAIK the fov is already there but not visible so maybe just as a shadow on the ground.?
Another thing is the ability to defuse explosives. For the moment if I set the timer to 1 and in the next turn I cant or just dont need to use the explosives anymore (specially with high explosives I might be withing blast radius) there is no option to defuse the explosive but only to throw it.
Cheers
