Difficulty options

You can play most missions on easy, medium, hard, extreme or impossible. Some demo missions only have a set difficulty. Medium is the recommended choice for first-time playing.

Some elements in a mission may change on higher difficulty.

• Resources are less abundant.

• Objectives are more difficult to complete.

• Enemies appear in larger number. Adult and larger variants become more common and appear sooner.

• Preparing periods and intervals of attacking waves is shorter.

• Titans are have greater size and health.

• Enemy colonies are more aggressive, have greater headstart and cheat more frequently.

Enemies have halved health and give doubled food amount on easy. Unique enemies may appear in some missions only on impossible.

You can't save in the middle of any missions.

Achievements

You can earn achievements by completing extra objectives before beating the respective mission on the designated or higher difficulty. Only story missions and holiday missions have achievements.

Achievements don't affect rewards or story progression. You can earn achievements when you are in new game plus.

You can enable achievement tracking to know if you meet or fail any requirements during a mission.
