you know that there are several types of environments:
fire, ice, massive, dark
But my idea will be that there will be a distribution of environments according to complexity and the addition of new ones.
New environments:
Time fluctuations - medium threat (veteran difficulty)
Description:
Sometimes during a mission with a given environment the game will either speed up or slow down
meteor shower - medium - complex threat (Virtuoso difficulty)
Description:
Occasionally, like terminator chickens, meteorites will fly individually or in groups
Clucker’s Madness - Medium Threat (Veteran Difficulty)
Description:
Enemy density increased by 25-50%
Distribution of existing environments:
fire - medium threat(veteran difficulty)
ice - easy threat(rookie difficulty)
dark - hard threat(SSH difficulty)
massive - easy - medium threat(seasoned difficulty)
