Four quite interesting weapons here, all with a fluidly organic appearance that looks quite alien.

There are two firearms - one longarm and one sidearm - a sword and a battle axe. If you wonder about the latter two, consider a boarding action in space. You do not want projectile weapons making holes and letting all your air out!

They are nicely drawn and could serve to illustrate a weapons list or even feature on your character sheet or reference cards to show just what you are packing!
