.:=Equipment=:.

=Gear=

Binoculars - Roll perception at a distance of up to 120ft without penalties. Built-in camera.
Combat Stimulant - Discontinued after their manufacture was made illegal for compelling reasons... but the copious existing supplies can still be traded and used. Immediately heals as though you had a full rest and provides a +2 bonus to attacks and damage for 2 hours. The next time you rest, you do not heal.
Medical Kit - Contains 10 uses. By rolling Medicine with a result of 10+the wound's damage, a wound can be removed, and HP restored equal to half of what it originally dealt. Even on a failure, a treated wound will not fester. 2 uses can be spent on a dying individual with a Medicine check to restore HP equal to half the check's result. If this healing brings them to 0 HP or above, they do not die.
Security Tools - A set of intricate, versatile, and usually reusable lockpicks that can be used to pick many different types of locks.
Glow Lantern - A bioenergetic lantern with built-in solar panel and adjustable light.
Weight-Distribution Pack - Increases carrying capacity by 15lbs when properly packed.
Bedroll, Sleep, and Mess Kit - Grants a +4 bonus to endurance when sleeping when applicable, and allows sleeping without any check at all in safe conditions.
Commlink - A hardened cell phone, radio, and internet uplink. Built-in headphones and microphone tech.
Pocket Computer - A very small but significantly more powerful version of a commlink's computer. Hardened so it won't easily break. Integrates a sample analyzer and onboard AI for diagnostics and assistance.
Rations - Enough food, water, and vitamins for 24 hours of action. Middling taste.
Ammo Pack - Your weapon needs it to function. Unless it uses bioenergy. One pack fills a weapon to its capacity, afterwards it must be reloaded as a standard action. Ammo is designated per weapon type when purchased (sidearm, automatic, shotgun, sniper rifle).
Temperature Cloak - Grants a +4 bonus to survivalism for resisting heat and cold.
Personal Protective Equipment - Heavy-duty gloves, steel-toed boots, combat helmet, etc. Grants 2 extra damage resistance that only applies to critical hits.
Proximity Alert - Laser sensors often set up to guard chokepoints or campsites. Can either make loud noises or send silent alerts.
Multitool - The modern space-age swiss-army knife. Can be used as lockpicks at a -4 penalty.
Repair Kit - Contains 10 uses. Can be used to repair objects with a sufficient repair roll, plus be used in conjunction with scrap or other such materials to make field repairs to more sensitive equipment. When equipment breaks (often from a natural 1), roll 1d10 for severity. 10+severity is the required result to fix the damage. If the check fails, 10+severity becomes the damage of the gear, and you instead restore an amount of that damage equal to your Repair ranks, and can spend more repair kit uses to do so again until the damage is gone and the item is repaired. A natural 1 on a repair check sets the item's severity to 20. A 10 on severity followed by a failed repair roll destroys the item.
Stealth Device - This is too expensive for you. Generates a field that hides the user or a small location. Works much better when stationary.
Portable Solar Panel - Charges up objects that use charge.
Rope and Grapnel - Lightweight yet strong cord that must be thrown to hook onto something. Contains 120ft of rope.
"Baker's Dozen" - A standardized set of explosives for a variety of situations. Contains 3 fragmentation grenades, 2 flashbangs, 2 smoke grenades, 1 pineapple grenade, 1 incendiary grenade, 1 cryogenic grenade, 1 emp grenade, 1 sticky grenade, and 1 claymore or shaped charge. Cheaper than taking them individually.
Creature Comforts - Everybody needs their own things. Take a -1 penalty to initiative when you are completely devoid of that which brings you joy.

=Armor=

None - Generally speaking, you are not usually advised to get into fights while naked. AC 14. Speed +10ft.
Sleek Suit - The lightest standard-issue armor. AC 13, damage reduction 1, speed +5ft.
Standard Armor - Standard-issue standard armor. AC 12, damage reduction 2.
Drake Armor - Heavy-duty heavy armor. AC 11, damage reduction 3. Speed -5ft.
Power Armor - This is too expensive for you. AC 10, damage reduction 4. Speed -10ft.

Protective Shield - Takes up a hand, but increases AC by 2 when wielded.
Energy Shield - This is too expensive for you. Bioenergy-based force field that grants 2 temporary HP per charge.

V = Vital link; usable up to Backbone+Bioenergy Weapons times per day. Using it further deals 1d3 nonlethal damage to the user that does not inflict a wound, but can be reduced by 1 by succeeding an Endurance check equal to 10+the number of times this check was made in the last 2 hours.

.:=Species=:.

Kwaise ( 'ku-aze' )
Often just called "space raptors" by humans both affectionately and derogatorily, past wars were brutal and memorable, but also a distant memory, and they're pretty much past all the bad stuff now aside from ribbing. They are digitigrade, have extremely small claws, dextrous hands, and come in multiple colors and sizes, occasionally even being striped or mottled like horses. They have feathery manes from their heads to their tails, though it's not uncommon for them to dye or pluck them for personal taste. The rare among them are occasionally psykers, and their society commonly reveres these individuals, especially those that have more noticeable power strength. This practice is dying down, and discouraged by the federation and most forward-thinking among them, but the idea is still extant in the culture.
⦿They can see better than most species in the dark.
⦿When below half health, they get bloodlust, and gain a +2 to attacks and damage, but can take time to stop being jittery, especially if they remain at lower health.
⦿They can jump twice as high and far as humans.

Ganvellien ( 'gan-vel-ian' )
Described by many humans as "alien dragonflies", these four-armed creatures are covered by slightly iridescent scales, and have two sets of gossamer wings on their backs. These wings grow back, but are vestigial outside of low-gravity environments, so are frequently removed or otherwise kept out of the way in high-gravity environments. Their heads are somewhat flat and pointed, and the rest of their body is similarly streamline, with two thin, symmetrical tails splitting from the same point near the base like a swallowtail. Due to the abrading dust storms and severe sunlight levels on their home planet, they are known for their comparatively rapid healing, and make have taken up careers on other planets in fire rescue. They finalized joining the federation relatively recently, and now they've been in for only a few centuries.
⦿Instead of healing from sleep, they heal 1 HP per hour so long as they've properly slept and had sufficient nutrition.
⦿They have damage resistance of 5 which only applies to heat and fire damage.
⦿In low-gravity environments, they can fly as well as they run.

Human ( 'hugh-mann' )
One of the founding members of the federation, they're not perfect, but they're doing better now than they used to. With so many species and competing interests in the federation, it's difficult for any one group to successfully get what they want... but with the prosperity from having so many worlds and species combined together, it's easier for everybody to successfully get what they need. They are often viewed by the wider galactic population as either noticeably insightful, noticeably selfish, or both. Aside from some very rare scientific curiosities, they are not known for being psykers.
⦿Opposable thumbs and pursuit tracking are pretty cool.
⦿They brought jungian psychology to a galaxy that really needed more frameworks for discussing mental health.
⦿They make really good entertainment, seriously check it out.

.:=Action Resolution=:.

Attack rolls: 1d20+Skill Rank
Skill rolls: 1d20+Skill Rank

On a natural 20, you hit with an attack and deal double damage, or succeed in your task for a skill roll (or make significant positive headway if what you were attempting to do was impossible).
On a natural 1, something goes wrong. Oftentimes a piece of equipped gear or gear that was involved in the action becomes damaged, and cannot be properly used until repaired, though other appropriate fumble results can also happen.

In combat, you have a swift action, a move action, and a standard action, as well as any number of immediate actions.
You can use a standard action as a second move action, but not vice versa.

When injured, note how much damage the injury dealt, and track how long it's been since the wound was inflicted. Track each wound individually. Individuals reduced to 0 HP or less fall unconscious. Individuals reduced to -HP equal to their Backbone die unless they succeed on a DC 10+the number of times this check was made Endurance check every round.
