Walks too far? I don't even make it off the ramp sometimes! Ah, well. I suppose that's XCOM for you.
In Vanilla it was strange that my soldiers were shot in the first turn while descending the ramp of the skyranger. However in openxcom it is exactly the contrary. In my first missions I was losing between 2 or 3 men in the first turn because of this.
To avoid this, since then in my first turn I throw a smoke granade into the ground infront of the ramp and then start the deployment on the second turn. Since then I don't remember losing a man on the ramp, I became too cautions in that sense (I play in auto-ironman mode).
In OpenXcom I have also noticed some positions inside the UFOs are always covered and there is no way of seing the alien first to kill him. He will always be there waiting for you and killing your first man. So you have to figure out new strategies there, granades, mind control units or other explosive amunition
.
I must admit I love that there is an improved AI. In vanilla after a while it was a little bit embarrasing seing the aliens not doing anything to try to win the battle, just stay there and shoot if you were around running.
