The Global Warming Event is an idle/upgrade-based Event, similar to the Clean Energy Event. The player can buy/level up one of four upgrades: Pyrotechniques, Tire Prefire, Toxicology, and Potent Fuels. Each of the upgrades generates Pollution Points (PP). Pollution Points are used for buying/leveling up upgrades. For generating enough PP, players can claim rewards.
Mechanics[]
- Pyrotechniques increases Polar Melting, which causes 100 pollution per minute each
- Tire Prefire increases Tire Fire, which causes 500 pollution per minute each
- Toxicology increases Dumping, which causes 1000 pollution per minute each (starting at 2500)
- Potent Fuels increases Brownhouse Gases, which causes 2000 pollution per minute each (starting at 10,000)
Therefore, one suggested upgrade order is the following:
- If Toxicology costs less than half as much as Potent Fuels, upgrade Toxicology.
- If Tire Prefire costs less than half as much as Toxicology, upgrade Tire Prefire.
- If Pyrotechniques costs less than one-fifth as much as Tire Prefire, upgrade Pyrotechniques.
- Otherwise, upgrade Potent Fuels.
