Well may be the theme of redneck abduction led me to this idea.
There are two types of ordinary mission in xcom:
- crashed ufo discovery
- non-crashed ufo discovery
In case ufo was not crashed operatives can catch cosmites with their pants down.
ie aliens can be cought in the process of conducting their eivil buisiness. The process of abduction istelf can be implemented!
Note, aliens behavoir can be completely different depending of what is their situation, plan and expectations! If they have crashed then some cosmites are fixing soucer and some are hanging around defending the perimeter. Or i more like an idea that they are hanging around with a reason human can not undarstand at all
Also the most important thing is what should be the behavoir of non-crashed abduction ship? Imagine you have killed 1-2 aliens when approaching to ufo at nigh and then it started to lift off. I would poo my pants if this have happened when i was 10 yo playing xcom. Completely new turn.
