Hi, a couple of ideas that came to my head:
1. I noticed some kind of exploit that allows a player to find out if other alien bases are present on the planet.
For example if he sees a base like "Alien base - 3", and it is the first base he discovers, there are obviously two more somewhere.
Apparently, game numerates alien bases in order of "foundation", not in order of the player discovering them - which would be more realistic.
2. This is more like mod request - why on earth (he-he) xcom operatives cannot use an instrument that all special teams use for ages - combat shields?? (or ballistic shields or whatever)
Almost every suicadal entree through UFO door adds a grey hair on my head. Adding some kind of front protection could greatly increase the survival rate in such situation, don't you agree?
To keep the balance there can be added some limitation, like sertain amount of shield in transport or/and, for expamle, the stand with shields occupies a place for 1 solgier (weighing a lot / giving penalty to aim, etc.).
Shields themselves, of course should not be a panacea, being able to withstand only sertain amount of damage.
Also sientist can research reinforced shield after alien alloys.
Thanks for your time.
