Technology has improved significantly since the Tribes relocated to the Sunless Sea, and is now roughly equivalent to the beginning of world war 1. Here's a list of the most important pieces of tech: Ironclad Ships: This kind of tech has been around for about 30 years. They're more expensive than traditional boats but are more durable. Diving Suits: These outfits are large and clunky, but they allow you to breathe underwater and protect you from waterborne toxins and poisons. An essential purchase even if you're a seawing; as mentioned in the Tribes project, seawings have trouble breathing the water of the sunless sea, though they've gotten a little better at it over the years WW1-era Firearms: The rounds these things fire include the gunpower used to propel them in the casing. This tech is relatively new, having been around for only 15 years, but is already in common use. Note that most weapons are not capable of rapid-fire yet. Harpoon Guns: These spring-operated weapons have been in use for about 20 years, and are fairly popular among those who hunt creatures of the Sunless Sea for a living. Machine guns: These cutting-edge pieces of tech have just hit the market and are not very common. They have a very fast fire rate, but are heavy, prone to malfunction, and too bulky to carry around by hand; instead, they're generally mounted on vessels or forts. They also guzzle ammo at an incredible rate.
