A series of decals representing an alphanumeric alphabet that we can put on surfaces to create signage. This can be used mark things like a Trader, Safehouse, Teleporter, PVP zone, etc.
If the concern is that it could be abused I would settle for just common useful words stylised to fit the look/feel of the DayZ universe. For example:
- TRADER
- LOOT
- GEAR
- GUNS
- AMMO
- MEDS
- PVP
- PVE
- SAFE
- HOUSE
- BASE
- PLACE
- ZONE
- HERE
- AND
Plus additional arrows for pointing such as straight, curved and angled.
Result would be a much more immersive experience for players with less complexity and performance issues for modders.
