Oh right, I was supposed to explain some of the rules.
Well if you're familiar with Dark Castle, it works pretty much like that.
The combat is slightly different due to ranged weapons available and damage type. One major difference is the option to "flank" an enemy during ranged combat.
Doing this puts you at risk in getting hit as you get into position. You also don't attack that round, but next round you get the chance to do a more damaging attack with no chance of getting hit.
There is also damage type which is energy, ballistic, and explosive. Some enemies are going to be more or less resistant to different types.
Also your ranged weapons do not have unlimited ammo and you're going to have to reload them every now and then. Typically a weapon might have 1 or 2 bursts before needing to reload. However, since I'm going to be doing all this book keeping, we can just assume you reload as needed.
There is also a medical drone which is essentially the "Take cover and heal" option during combat. Obviously though if you're the only one left in the group, you can't do this.
Finally there is close combat, which works just like it did in Dark Castle. Caving in someone's skull is a simple affair, so the intricacies of damage type don't apply here. You're just using brute force (which is hopefully a lot of dice) to take down your opponent.
Of course things will be explained as needed during the game.
