Killstreak kit
“ | The loot you'll get from completing a Tour of Duty will work a bit differently for the Two Cities Tour. Completing a Two Cities Tour automatically grants you a Killstreak Kit, which you can apply to any weapon to transform it into a Killstreak weapon. Completing the Tour also grants you a fabricator and spare parts that you can use to craft progressively rarer Killstreak Kits, which will add cool visual effects to your weapon and eventually even your character.
