Rewards

The game calculates how many Coins Coins, Gems Gem and you receive based on how many waves you survived and if you won a match. During periods of 100% more (Friday – Sunday), any earned is multiplied by 2x through the XP Boost modifier. The VIP gamepass also multiplies any earned by 1.25x through the VIP Boost modifier. These two boosts are additive. Regular boosts are multiplicative with other modifiers present on this map. Any rewards that end in a decimal point is rounded down, no matter the first figure of the leading decimal.

Strategy

Most ground towers are suited for this map, due to the path's nature on cutting back on itself quite a few times. However, be aware of the limited space available for towers. Later on during the game, sell unnecessary towers to make space for essential ones. If you need to bring Rangers, make sure to sell any Snipers that may occupy the mound and cliff to make space for Rangers. The DJ Booth can massively benefit towers, as the map itself is quite small. A long-range tower, like the Ranger, will be able to reach the entire map with a well placed DJ Booth. As the map is quite short, you may want to use the Electroshocker, Sledger or Toxic Gunner to slow down enemies.

Patch history

This first version of the map was once used as the example for the Tower Defense Simulator Map Making Kit. Grass Isle is used as the default background for player profiles, though an outdated version of it is used. On the third version of the map, there is a humanoid figure wielding a scythe. This humanoid has a similar skin tone and clothing as the Slasher. On 7th of March 2022, this alongside Wrecked Battlefield, Crystal Cave and Sacred Mountains were accidentally left as the only survival maps in the game. It alongside Crystal Cave were the only playable survival maps. This was later fixed on the same day.
