Wearing protective headgear is a must, I think.
“If you can only choose one piece of armor, choose headgear.” – Matt Easton, HEMA instructor
If we can integrate info in that headgear with our space-age tech, all the better I think. Having to look down or take your hands of a weapon to check your handheld device to see some basic info is counter-productive, I think.
The weapon designs indeed do look awesome. I like all of them, and would love to use all of them. The main question is if we’re shooting beams or projectiles? Since we have both in space combat, we might have both or just the beams in the close-quarters combat. When talking about close-quarters combat in a spaceship or a spacestation, one must think about breaching the hull from the inside. Therefore, projectile weapons increase the risk of damaging the hull. So, if we only have a beam weapon, does the size matter? Will a beam emitted from a small weapon be equal or close enough to the one emitted from a bigger weapon? Is a beam emitted from a small weapon enough to maim or kill a person? Do we need rifle-sized weapons to fight Torgoths?
What about hand-to-hand weapons, either blunt or sharp? Do we have some vibro-blades or something like that, or do we rely on cold, hard metal or plastic? Do we wear small swords or long knives?
