Just letting ya know beforehand, but the character this is for is gonna be a bounty hunter. Not a merc, a bounty hunter; he doesn't ally with factions, but instead merely accepts individual contracts, usually assassinations and the such.
Hunter's Helmet:
A custom-made bounty hunter's helmet/mask. Comes equipped with a gas-mask, x-ray, night vision, and a two-way radio/headset, to allow communications between him and his employers. It also can enhance and magnify the image at his command, enabling him to get a better look at further off targets. Its very durable, and the material can survive blasts from battle tanks of many factions, even non-earth ones. The wearer, well, maybe not so much, if the rest of the armor isn't made of the same stuff. The helmet has a generator independent of that of the main armor, being two different pieces of equipment that can be fitted together, allowing the wearer to still observe their surroundings even if the suit's power source should fail.

Hunter's Armor:
A full-body armor armoring made from the same durable compound that makes up the Hunter's Helmet. It also has a variety of technological enhancements, such as a device that can charge the left arm with electricity, a flamethrower on the other arm, mini-thrusters on his feet, and a miniature generator to power it all. The suit itself is actually quite heavy, but due to the internal workings, it is made to hold itself up; you could say it moves with its wearer to relieve the weight and power his close-combat strikes. Due to these workings, it DOES enhance its wearer's strength, and it is still heavy, which means that it can be used to smash through concrete, hulls, ect. When hooked up to the helmet, they can operate as a space/deep seasuit, but because of its sleek styling, it doesn't hold much air. Because of its weight, if its power source is cut off, it effectively traps its wearer within it, though, so it could be considered a double-edged sword.
Black Platinum: This is the name of the alloy used to produce these armors. Its a very strong metal compound, but its also extremely heavy; a small inch-diameter ball of the stuff weighs as much as a small car. Its hard to use it to produce stuff, but when it is used correctly, its extremely potent. Only dent-able at extreme temperatures, extremely resistant to fracturing, ect. Preffered material for the equipment of a certain bounty hunter...
There's a bit more, but Im running out of time on the computer. The rest is weapons anyways; this stuff is the main deal.
