[@ClocktowerEchos] I know a few things of Dead Space like most of the weapons that you come across from Dead Space 1 and 2 hard mostly either engineering or equipment like the plasma cutter would be an engineering tool, while the line gun was used for mining. The pulse rifle was pretty much the only military weapon. Though its been awhile since I played the games there might be more.

The location of the RP is placed on the space station called Titan Station, or you can simply just call it the Sprawl which is on Saturn's Moon titan which was is the site of the first planet crack.

And there are four types of RIGs, the engineering RIG which is used by Isaac Clarke and is also used for mining. There is the Security RIG which would be what Sprawl security personnel would wear. And theres the Military RIG which is what the soldiers would normally wear. Then the Civilian RIGs which don't have any armor at all. Hope that helps. :)
