With the assistance of AI and tech sensors in your suit or implants you can defend yourself from attacks from both flanks and rear to cancel your opponents normal attack bonuses.
You use your autopilot defence against all enemies that are attacking you. Consult the DR-table below before rolling. Basic DR is 100 against 1 opponent. DR increases with +20 per extra opponent.
As a standard effect you negate 5 points in bonuses. Flank attacks will thus be made at +10 (instead of +15) and rear attacks at +20 (instead of +25).
For each Success Rate 15: You negate an extra +5 bonus. (SR 30 = +15)
