Verbal briefing of rules/objectives
When you play Co-Op bot destruction or any of the objective driven match types (Missile assault, Siege ect) have the instruction on the right hand side read out verbally with a blinking highlighted box around each area its talking about.
New players seem not to even notice the instructions on the right.
If they check the do not show this again box then disable the visual and verbal instructions until turned on in the options again.
