Mechanics

Please note that all mechanics are only active when Atmo is running.

O2 Management

As O2 depletes, O2 Recovery Rate is reduced by up to 60%. If O2 falls below 10%, Sprinting Speed is reduced by 20% and Jump Height is reduced by 60%. Using a Boost Pack will drain a small amount of O2.

CO2 Management

CO2 Recovery Rate is reduced by 40%. Getting hit by enemies triggers a small increase in CO2. Accumulate CO2 over time while performing strenuous activities like running, sprinting, or sneaking. Accumulate a portion of CO2 instantly when sliding or mantling.

Installation

Atmo can be installed anytime. It will begin running whenever conditions are met.

Compatibility

Atmo is generally compatible with everything. It is however redundant with "O2 Consumption" systems like Real O2 or Realistic Oxygen Meter.
