No motion tracker, period.
How about trying maybe pistols on but headshots disabled? That's still a thing right?
I'm pretty sure I saw headshot immunity in the settings for H2A. I like this suggestion.
Updated!
My suggested ODST game type
-Silenced SMG starts
-Pistol as secondary weapon
-No shields
-90% movement speed
-Force armor colors if possible (steel vs silver?)
-No motion tracker
-Headshot immunity for all players
Also, what about on map weapons? Default for the map or human weapons only?
