  • Defend ~mission(Location) From Mercs [250 Rep] [BP]* (Headhunters)
    Description
    So, I thought we had done a good job of keeping things on the quiet side, but looks like the fact ~mission(Location|Address) has Headhunters ties has gotten out. Now there are some heavy operators causing major problems there, targeting the ~mission(Objects) and generally causing me a massive headache. With the amount of firepower these interlopers are packing, you're gonna need to bring along a crew of your own to pull this off. Especially since I need you to be protecting any friendly ships that need help. This op needs to go off without a hitch, so I’m offering the main contractor ~mission(ScripAmount) Council Scrip for a job well done. Stows out.

  • Guard ~mission(Location) From Rivals [300 Rep] [BP]* (Headhunters)
    Description
    The maintenance and reliable function of ~mission(Location|Address) is pretty darn important to the Headhunters, but this rival crew seems determined knock it out of contention. They're on site now, targeting ~mission(Objects) there. Protecting the site, and any friendly ships, in the area is important enough that I want you to bring some reliable backup along when you go and terminate these nullbrains. To prove just how serious we are about getting this done right, the main contractor will earn ~mission(ScripAmount) Council Scrip for making sure absolutely nothing goes wrong. - Stow Reputation Awarded: 300 Potential Blueprints Awarded from Veteran Contractor level variants [Regional Variants] example locations: Nyx System, nyx, Nyx - Cryo-Star SL (Cooler) - Winter-Star SL (Cooler) - Kelvid (Cooler) - Cryo-Star (Cooler) - Winter-Star (Cooler) - BlastChill (Cooler) - FlashFreeze (Cooler) - Endo (Cooler) - Cryo-Star EX (Cooler) - Winter-Star EX (Cooler) - FullFrost (Cooler) - WhiteOut (Cooler) - Taiga (Cooler) - Cryo-Star XL (Cooler) - Winter-Star XL (Cooler) - ColdSurge (Cooler) - FrostBite (Cooler) [Regional Variants] example locations: Nyx, Nyx I, Nyx III - Tarantula GT-870 Mark 1 Cannon - Tarantula GT-870 Mark 2 Cannon - Tarantula GT-870 Mark 3 Cannon - YellowJacket GT-210 Gatling - Scorpion GT-215 Gatling - Mantis GT-220 Gatling - V880 (Radar) [Regional Variants] example locations: RAB-ROTH, RAB-NOVEMBER, Monox - DuraJet (Powerplant) - ZapJet (Powerplant) - WhiteRose (Powerplant) - SparkJet (Powerplant) - Lotus (Powerplant) - SparkJet Pro (Powerplant) - TigerLilly (Powerplant) [Regional Variants] example locations: RAB-FOXTROT, Checkmate Clinic, RAB-KILO - AD4B Ballistic Gatling - AD5B Ballistic Gatling - AD6B Ballistic Gatling - V801-11 (Radar) - V801-12 (Radar) [Regional Variants] example locations: Magda, Ita, Hurston - PIN (Shield) - 5SA 'Rhada' (Shield) - 6SA (Shield) - HEX (Shield) - WEB (Shield) - 5MA 'Chimalli' (Shield) - 6MA 'Kozane' (Shield) - BLOC (Shield) - STOP (Shield) - 5CA 'Akura' (Shield) - 6CA 'Bila' (Shield) - ARMOR (Shield) - GUARD (Shield) [Regional Variants] example locations: Ita, Aberdeen, Hurston - SW16BR1 “Buzzsaw” Repeater - SW16BR2 “Sawbuck” Repeater - SW16BR3 “Shredder” Repeater - Vigilance (Radar) - Devoue (Radar) - Tige (Radar)

  • Stop Rival Attack at ~mission(Location) [200 Rep] [BP]* (Headhunters)
    Description
    There's this small gang that continues to be a thorn in our side, and the bastards have just ambushed some friends over at ~mission(Location|Address). Seems like they're doing their best to destroy the ~mission(Objects) there. I need you and whatever crew you can muster on site stopping these mungers from blowing everything up and protecting any friendly ships that need a hand. Handle this right and I’ll give the main contractor ~mission(ScripAmount) Council Scrip. - Stows Reputation Awarded: 200 Potential Blueprints Awarded from Sr. Contractor level variants [Regional Variants] example locations: Nyx, Nyx II, Nyx System - Cryo-Star SL (Cooler) - Winter-Star SL (Cooler) - Kelvid (Cooler) - Cryo-Star (Cooler) - Winter-Star (Cooler) - BlastChill (Cooler) - FlashFreeze (Cooler) - Endo (Cooler) - Cryo-Star EX (Cooler) - Winter-Star EX (Cooler) - FullFrost (Cooler) - WhiteOut (Cooler) - Taiga (Cooler) - Cryo-Star XL (Cooler) - Winter-Star XL (Cooler) - ColdSurge (Cooler) - FrostBite (Cooler) [Regional Variants] example locations: nyx, Nyx I, Nyx - Tarantula GT-870 Mark 1 Cannon - Tarantula GT-870 Mark 2 Cannon - Tarantula GT-870 Mark 3 Cannon - YellowJacket GT-210 Gatling - Scorpion GT-215 Gatling - Mantis GT-220 Gatling - V880 (Radar) [Regional Variants] example locations: RAB-FOXTROT, Checkmate, Checkmate Clinic - DuraJet (Powerplant) - ZapJet (Powerplant) - WhiteRose (Powerplant) - SparkJet (Powerplant) - Lotus (Powerplant) - SparkJet Pro (Powerplant) - TigerLilly (Powerplant) [Regional Variants] example locations: RAB-KILO, Cluster NBD-102, RAB-FOXTROT - AD4B Ballistic Gatling - AD5B Ballistic Gatling - AD6B Ballistic Gatling - V801-11 (Radar) - V801-12 (Radar) [Regional Variants] example locations: Arial, Magda, Hurston - PIN (Shield) - 5SA 'Rhada' (Shield) - 6SA (Shield) - HEX (Shield) - WEB (Shield) - 5MA 'Chimalli' (Shield) - 6MA 'Kozane' (Shield) - BLOC (Shield) - STOP (Shield) - 5CA 'Akura' (Shield) - 6CA 'Bila' (Shield) - ARMOR (Shield) - GUARD (Shield) [Regional Variants] example locations: Arial, Ita, Aberdeen - SW16BR1 “Buzzsaw” Repeater - SW16BR2 “Sawbuck” Repeater - SW16BR3 “Shredder” Repeater - Vigilance (Radar) - Devoue (Radar) - Tige (Radar)

Quality Calculator

Beta Beta calculation: best/worst material appears to fill each slot from your highest/lowest quality stacks until the slot is full. Average quality is weighted by amount used. Example: 2 units at 865 Q plus 5 units at 797 Q gives 816 Avg. Q. If two slots affect the same stat, their deltas are added together.
