t;'dr Hello Kitty Paint Jobs!

Go to your assets and have a look at a fully fitted robot. Perpetuum is modular by default, like Annihilator pointed out. It's just a can of worms balance-wise.

The hybrid robot system is IMHO not releaseable in its current form.

while a small choice of hybrids does look nice, most of them are horrible kitbashed abominations (look at the lithus chassis with legs on that screenshot...)

ontop of that, intersection between body parts that dont fit together are not nice either (eg. seth head on intact, would plow in ground all the time)

The only reasonable and logical implementation of the Hybrid system that i came up recently, was adding interchangable body parts that only slightly change the mechs appearance (eg, a slightly altered, beefed up chassis that has more hitpoints). You dont interchange parts between mechs, but have a selection per mech.

like i would like to see a 6-legged Seth with an array of small weapon mounts on one side, and a large mount on the other side, with an independant turret (2nd player ) slot ontop.

it reminds me of Morrowind a bit - the same armor looked different on a khajit than it looked on a human. Not only in Morrowind - it is a common thing to make armor change their shapes in RPG then it gets weared by a woman or by a man.

It just wouldnt be me without coming up with some way of visualising what is in my mind. Check this:

The alterations can be huge and the way they are determined could be by a stat or static (as whenever a module gets connected to another particular module it transforms into a particular shape).
Stat-based (like encumbrance) system would be a lot better imo. I am getting it all worked out in my head as I speak so I may be making another post soon
