Red versus Blue
Both teams field the same eight heroes. Players switch freely between them; any hero nobody controls defends the base as an AI. Every level up to 10 brings more health and damage.
Team-based multiplayer game
Two teams, eight heroes each, up to four players per side. Build up your base, dig underground for gem ores and bring down the enemy's Elder Stone.
The game
Both teams field the same eight heroes. Players switch freely between them; any hero nobody controls defends the base as an AI. Every level up to 10 brings more health and damage.
Axe and pickaxe instead of a weapon: wood, stone, crystal and water have to be carried to the building plot. Heavy loads slow you down, and whoever dies loses their load.
Four rock outcrops lead into a tunnel system. The gem ores down there do not grow back, and nobody gets at them without a crystal pickaxe from their own forge.
Every 26 seconds, waves of creatures cross the center line. Towers only fall in order. When the enemy's Elder Stone falls, your team wins.
What comes after that is on the timeline.
