I'm curious to see how people have handled void combat (fighting in a void suit in space, not starship combat) since the opportunity has presented itself more than once in my game. How easy would it be for a character to rupture his void suit? Would there be any penalties to movement or accuracy?

I, personaly, have not actualy run any personal combat in Void conditions. However, because of the dangers of Void Suit rupture, I'd assign it as an additional Critical Hit effect. That way their wounds still provide them some protection in combat, but the harsh condidtions of the void still have effect.

I just ran a void combat scene 2 months ago. The cool thing is that you can start playing with the environment and the inestability of: temperature, gravity, pressure, atificial lightning, vacuum, etc. Well Im an engineer so I find that super cool hahaha At high temperature, the SP Amunition may explode, at a ver low one the Laser Amunition may not work (cause they are like batteries in winter), without gravity is really complicated to move for the not-void born characters, etc...

Now, about the suite... I recommend you to use the quality status (excelent, good, average, poor) to define penalties or even some bonuses. I also recomend you to consider the suites as a mechandrite implant for the matter of damage. This means, that the person is going to receive the damage, not the object. This will make the scenario simplier and you can focus more in role-playing stuff and less on mechanics.

Have fun and keep rolling!!!
