Environmental suit

The Environmental suit is a Strife item that protects the user from toxic water and radiation, and gives total immunity to players' and Crusaders' flamethrowers. When exposed to toxic water or radiation for more than 30 seconds, the player begins taking damage (which can be reduced by armor) directly proportional to the exposure time beyond the initial 30 seconds. Using an environmental suit prevents this damage from beginning or accumulating further, but it will not prevent any exposure damage that has already been accumulated.

Poison exposure and radiation are indicated by a flashing green tint on the screen. Once 30 seconds have passed, the screen stops flashing and it becomes solid green as damage begins to be taken. Damage will cease when the screen starts to flash green again.

You can hold a maximum of five environmental suits, each of which lasts for 80 seconds. The armor store in the town sells these for 25 gold per unit.
