Hello fellow Graalians!
Punctur here again with another idea. I was thinking that in the PK Arena or even in the missions or PvP arenas, there could be indicators for health, ammo, grenades, etc. The indicators could glow hot red when you go near them and colder when you go farther from them. If players don't like the indicator settings, then there could be a tab to turn them off in the options menu.

Thanks! Hope to see some positive feedback from the gang,
Punctur.
