Tunnel Vision

Check out Fallout’s video timestamped to start of Tunnel Vision testing.

Tunnel Vision - Reloading after defeating a target greatly increases target acquisition and aim down sight speed for a short duration.

• ADS improvement is a “minor bump”; definitely not Shapshot.
• Slightly widens your Aim Assist (i.e. bullet magnetism) cone giving you a more generous area of where any bullet you shoot can hit.
• Duration of 5s.
• Does not stack.

From the DCP “Firing Range” podcast; an interview with Bungie sandbox leads:

Tunnel Vision grants +20 Aim Assist, +20 Accuracy and also a small multiplier to auto aim and magnetism cone angles
