How it plays

You begin as a fly, one of the smallest creatures in a shared arena. Eating the right food helps you evolve into bigger creatures, each with more options and more threats.

Survival has two parts. You need to find water to keep going, and you need to avoid predators: creatures that are higher on the chain than you. Hiding and choosing when to move matter as much as speed.

Other players share the arena, so the situation changes all the time. The long-term aim is to become the strongest creature on the map.

Tips for a first session

1.

Keep an eye on water. Running low while being chased is a common way to lose a strong creature.

2.

Move along the edges of busy areas instead of through the middle.

3.

Eat steadily rather than chasing single pieces of food across the arena.

4.

After evolving, check which creatures are now a threat; the list changes with every stage.
