The developers of Crazy Defense Heroes have started the Carnival Invasion event at the beginning of this month.

The event was announced near the end of last month and is set to last from October 1 to October 10, allowing players to gain various rewards across 4 difficulty modes until the end of the event. In the lowest difficulty mode, Normal, players have a chance at getting three 2-star cards, one of which is a Tower Card called the Illuminator Tower, while the other two are Spell Cards called Egg of Mana and Glyph of Fatigue. The Illuminator Tower can detect and attack invisible enemies, while the Egg of Mana basically gives you free mana and the Glyph of Fatigue lets you cast a circle where all enemies in it get slowed down. 3-star versions of these cards are available in Hard mode, while 4-star variants can be found in Crazy mode. Nightmare mode on the other hand includes 120k Gold, 120 Gems and 110 Legendary Jades as rewards. Players can also purchase a Carnival Chest that is only available for this event by paying 600 Gems to get unique rewards.

Crazy Defense Heroes is a free-to-play 2D tower defense title available on Android and iOS devices via the Google Play Store and Apple App Store respectively. Players can connect their account with their wallet on the game’s official website and claim play-to-earn rewards by passing KYC verification and holding a TOWER Battle Card NFT on the Polygon network.

The game’s new Clan Quest Season, Lookout Season, is currently ongoing.
