Melee reactions (bug?)

[BenKirbyTennyson]

Heya,

 I have run into a situation in vanilla, where I am reaction-attacked by a Chryssalid.
The Ufopaedia states that "Units react using Snap Shot ONLY", which would rule out melee attacks, no?
Don't know if this is intended behavior or not.
I have uploaded a savegame here:

Just go down the elevator with the unit that is active as soon as the game is loaded and it will be killed by a melee attack.

Same happens with reapers. I think, that's intentional.

Intended behavior.  The snap shot rule only applies for ranged weapons, and OpenXcom has improved melee behavior including reactions.

In addition to melee reactions, other non-vanilla behaviour I've noticed is that terror units with arcing weapons will reaction fire even though traditionally they could not react. Aliens carrying blaster launchers/DPL launchers will also fire at point blank range, so you can no longer rely on their sense of self preservation as a last ditch effort to saving yourself.

I'm guessing these were a deliberate design choice. However I do feel these need to be toggle-able in the options like many of the other introduced features.

It was. The original game does not allow melee and arcing reaction shots, but OXC does allow them.
