Teaser Paragraph:
It's helpful to look at ET in terms of resources. You start with a fixed amount of hit points (HP), ammunition, sprint, and charge, among other miscellaneous things like artillery/airstrike timeouts, fire rate, class limits, panzer, etc. These resources are renewed at regular intervals either through respawn or just the charge/sprint/HP (medic) bar recharging. Time is a resource. These resources are multiplied by the number of players, except some shared resources like airstrike timeout and class limits.
