seems too complicated. it seems more doable to have a system where a human could get energy for an energy weapon or whatever by harvesting an alien body. that would be a simpler thing, and not as big of a balance issue, but I don't know if anything on the human side would make gameplay better without adding too much complexity.
on the alien side, I would really like to see something where you can use a human body. that could be a multitude of things, from a new class to a new building. some ideas:
A dretch could have a secondary attack at some point that would allow them to harvest a body and then have something cool. like additional hitpoints, temporary paralyzing poison or something. maybe a granger or dretch could burrow in a body and then explode it to create an acid bomb. or maybe turn it into a proximity mine. my personal fav would be if a granger could do an "infestation" to a person and then walk around in their body - either as a "stealth" thing, or as a way to send a kamikaze bomb straight into a bunch of humans. i for one would pick the granger-zombie as my new favorite class. :wink:
i'm sure most of these ideas are not very possible, but I think the idea of harvesting humans is so "alieny" that it would really add to the gameplay on that side. :wink:
more things to do on the RTS side of trem would be good, but i think it will be very hard to implement them while retaining the balance and feel of trem, which is already very good.
