Weapons
Weapons are going to use a procedural generation system to create an incredibly diverse variety.
Tiy talked a bit about this system in a QA Session
We have a procedural item system that produces items on the fly. I've got the rocket launcher stuff open right now, and there are MILLIONS of combinations of rocket launcher. The game even procedurally generates the graphic used for the guns, right now there are 21,000 different visual styles for rocket launcher. Then each of those styles can be coloured individually. By release time, there will be many, many more. And that's just for rocket launcher.
Research
You will be able to open a research lab on your space station that leads to a tech tree. This will be important for a variety of weapons, from small ranged weapons to mech suits.
You will be able to use any weapons that you find from enemy drops, but to create ammo you will have to do research. This enables certain weapons to be placed at key locations for missions and set pieces.
Types of Weapons
It has been confirmed that there will be melee and ranged weapons in game. There will also be battery powered as well as traditional projectile weapons.
One & Two Handed
Weapons will come in one and two handed varieties. When you equip two weapons, the left mouse button activates one, the right mouse button activates the other. You will be able to use multiple weapons in combination.
