I've been playing XCOM-type games for decades now, right from the original 'Laser Squad' on an Amstrad CPC (with a 4-track tape drive!), but one thing that bugs me is that while the characters can KNEEL they can't lay PRONE. After playing Jagged Alliance 2 and it's mods this gets even more bugging in XCOM as there are times when it would be useful, like hiding behind rocks and such or having a sniper on a roof.
Is this even possible with the Openxcom engine?
