How does armor work in Solar Echoes? (part 5)

Armor may be enhanced in various ways, most often for a price. Ballistic Resistance, for instance, grants armor an additional +1 bonus against ballistic attacks. Armor with the camouflage feature will grant a +1 bonus to Stealth. Other treatments include resistances towards electricity, energy, or fire type attacks, and fireproof armor prevents burning altogether. A Sealed Suit of armor can filter out most airborne toxins and will grant a large bonus against chemical and biological attacks. Some suits of armor include a helmet, which may also be purchased separately, and though this doesn't add to the total armor value, it will add a +1 armor bonus to attacks that specifically target the head. A combat shield can also provide additional protection—the user can gain 1 additional point of armor against a single attack, though this can only be used once per round and the user cannot wield any 2-handed weapons. Characters will need to decide which armor suits them best, and having the foresight to bring armor appropriate to a situation may mean the difference between life and death.
