Besides their weapons and gadgets, Rogue Enterprise operators can equip various perks that alter their performance and abilities. Like everything else in your loadout, the benefits are permanent once purchased. Additionally, weapon perks apply at all levels - for example, if you have Shredder Rounds and pick up another player's weapon, you will also have a large supply of ammo for that weapon.
Here are all of the perks currently available in Rogue Business, organized by their relative value.
Best benefits
The following benefits are must buy: Elude, Têtu, Agile Hands, Life drain, and Berserker. If your chosen thief can buy them, buy them as soon as you can in the game. They are guaranteed to either save your life or help you kill.
Important advantages
Sixth Sense is a double advantage, either to help you find targets or to avoid ambushes. It works even when enemies don't have line of sight for you, so it's basically a passive scan.
Bounce is an important benefit, but should be taken after purchasing other survival benefits. Unlike Evade or Headstrong, which help you survive, you must survive first to take advantage of Bounce Back.
Match specific benefits
Tenacity is literally still good, but especially against Dima, Scorch and Ronin.
Fill it's great to have, and especially against teams with Saint or Chaac, because finishing the opponents down is more important there.
Mask is useful in a variety of matchups, and a must-buy against Dallas, Talon, and Phantom.
Shredding rounds is really useful against Anvil, and moderately useful against things like Saint's drone and a number of deployable gadgets, although those are all very easy to destroy anyway. The side benefit of this perk - the extra ammo - is nice, but rarely comes into play.
Help is useful if your team does not have a Saint, or if you are a Saint, since it synergizes with your passive.
Situational advantages
Stalker is an advantage that grows with your skills. If you have a big goal, you can profit from it. It's also good for keeping you in ADS as you go through corners, but it's definitely not a priority buy for anyone.
Padded steps is a bit of extra help if you like flanks as it makes it easier for you to sneak up on people. That said, when the guns and explosions go off, other players can't hear you anyway, so the padded steps will very rarely be helpful enough to justify the cost. Only buy it if you are drowning under the money.
Follow-up tours is a polarizing advantage. This can technically be helpful, but a coordinated team doesn't need it. Not only that, but for the $ 10000 it costs, you can upgrade your primary weapon or purchase some other perk that would actually help you kill enemies instead of following them.
