Game modes

Arena Mode

Survive in a small, confined area as enemies spawn faster and in larger numbers. They do not grow stronger. Instead of receiving stat boosts when you level up, choose one of three perks to augment your abilities; there are 21 perks in total.

Adventure Mode

Explore a map twice the size of the Arena Mode map and collect six cores scattered across it. Bring them to the spaceship at the center, then activate it to reveal an area where you must endure attacks for a set time to advance to the next level. You can enter or leave this area at will, but the timer pauses while you are outside.

Enemies grow stronger as time passes. You decide whether to gather money and open item boxes around the map before moving on, or clear the level quickly. Adventure Mode currently contains 90 items.
