While battling your enemies in the field, you may run into issues hearing J.A.R.V.I.S. through your Repulsor Gear. If you're unresponsive for a few minutes, J.A.R.V.I.S. will repeat his instructions, but you can also try turning up the volume on your Repulsor Gear to ensure you can hear him clearly. If you're still having trouble understanding J.A.R.V.I.S.'s instructions, try restarting the mission over from the beginning.
