I can see the HUD change when a mortar is deployed in this video. Is there a way to change the HUD zoom during the game?
On PC the keys are
n to switch between small, medium, and large map size
m to switch between small, medium, and large map zoom
I don't know the controller button equivalents for this, unfortunately!
I found this controller layout scheme
Left Bumper Grenade Left Trigger ADS Right Bumper Melee, hold to equip knife Right Trigger Fire Left Stick Move Click once to enable run (continues until you release forward) Click and hold while ADS to steady aim (Recon) Right Stick Aim Click to duck, hold to prone Y Change Weapon X Reload B Enter/Leave Vehicle - Arm/Disarm M-Com A Jump/Vault Pad Up Turn on/off torch (when unlocked) Pad Left Deploy Ammo/Med Pack/ Radio beckon/etc... (when unlocked) Pad Right Deploy Defib/Rocked Launcher/Motion Sensor/etc... (when unlocked) Pad Down Change rate of fire Start Options menu Back Spot (press), Score board (hold)
But wow, I don't see the map controls anywhere. Maybe they couldn't fit it in there? Can you remap controls on the Xbox? Perhaps there's a way to remap the map zoom/size functions to one of the existing buttons?
