So... this morning I was thinking maybe we can streamline the turning part of ground combat.
Removing tactical depth is certain to attract naysayers, I myself has said no for other ideas too, so here is another option...
If we press Alt when we issue the order to move, the soldier will move sideway / backstep as necessary to keep their facing.
I won't mind if it cost a little bit of additional TU per tile. I find myself doing this on two soldiers for three turns in a row:
Walk to edge of rock wall.
Turn to peek, see nothing.
Walk one tile out of the wall.
Turn to look. May see enemy, may see nothing.
Turn back and walk to safety.
Turn back again to keep watch.
If we have sidestep, it'll be much simpler and efficient, and I hope more intuitive (less stupid) once the player get use to it:
Sidestep two tile out to look. If soldier see the enemy when it reach the wall corner with his first step, he will automatically stop.
Sidestep two tiles back to safety.
Side/back stepping is also useful in many tactical situations, so I think it'll see many use once implemented. It can also make light armours more maneuverable (full sharfe) than heavy armours (forward and backward 45' sharfe) and SHIVs (wheel or tracked).
Main cons that popup in my mind is... how about the aliens? The animation and intelligence is going to cost and they may look rather stupid
While I am writing this, I suddenly remember the soldiers seeking cover in Apocalypse when they come under enemy fire. If I remember correctly, they would turn back from enemy, run, turn, run, and turn back to face the enemy, all on their own. I already felt it was hilarious at the time.
