I like this idea but does requesting an epi-pen show your location on the map to anyone who has an epi-pen? The same way requesting a revive is shown to medics? @Peter Long
If so, then I can see some problems with people using the map to get people's locations who request an epi-pen. If not then +1 to its mechanics according to Muth's suggestion making it cheaper to get a last stand fighting and making dopamine worth more via hospital.
