Hi Prophet. Thanks for your report. Unfortunately this isn't a valid issue so I'll be closing this report. Grenades do get unlocked at level 80, maybe your friend was mistaken.

Thank you.

He’s right.

Thank you.

Have you tested this? Because I did and it’s a valid issue. It’s fixed already in the next update.
