A twin-stick top-down looter-shooter with increasing difficulty and some riveting music. You can find and/or upgrade gear during a run to keep up with foes and mazes of increasing complexity and challenge. The mazes gradually increase in size as you progress. Its not particularly deep but what is here is very fun and especially concentrated, so much so that I usually find myself thinking "just one more run". I definitely recommend it if you're looking for a no-nonsense looter-shooter experience.
