Missing missing SFX on shootout in Valhalla.

There is a missing sound effect in episode 3 chapter 4 of spartan ops. Right after you activate the turrets and clear the initial wave of covenant forces, infinity command launches pelicans that deploy several Mantis suits. The pelican and environmental sound effect are correct what is missing is the sound where the mantis itself it’s released and then hits the ground. Right in the middle of that Me and some friends noticed the missing “crash” sound such a heavy vehicle is deployed. Whe tried different things to try and solve the issue, for example, whe uninstalled and reinstalled halo 4 on our consoles, switched between HDMI and standart plug cables, and even threw in a turtle beach headset connected to the audio to Check if the sound effect was even there. There was no sound effect whatsoever. I know spartan ops doesn’t get to much attention compared to war games but still we would like to request if possible. A little help with that and other minor bugs. Thanks

Thank you for the report, we’ll pass this information to the appropriate team.
