Okay, further testing leads me to believe the ice battle suits may be slightly overpowered but it's not really a big deal. Lightning battle suits are a bit more iffy because 20 an is a lot, but it is mitigated somewhat by the relatively limited number of them you can have in one province. An Ulmish player could probably take on a jomon player reasonably well as long as the jomon player didn't have food items, but with them it would look pretty bleak. R'lyeh would need some really powerful magic backing them up not to get torn up by a jomon player it seems. I am slightly surprised though that battle suits are size 4, I'm pretty sure fighters are size 3 and I wouldn't have thought the battle suits would be bigger.

Anyway, I would either lower the damage 5-10 points or raise it 10 or more points and make it ap instead. Another option could be to make them fire once every two turns. But if you did any of those I would consider making them smaller because their supply costs rack up fast. If you don't change their size you might want to give battle suits a siege bonus because it takes forever to get through city walls with size 4 creatures without huge strength without diseasing yourself horribly. You should probably look at this more yourself, I'm not entirely sure if there's a major imbalance here, it does seem like there's potential though.

By the way, one of the floating predator alien cages has mod commands in its description. And because they're useless in space it might be good to make them not have ap in forests.
