# Free to Play, Play to earn Most of the P2E games require players to invest a fair amount of money to play. This unreasonable structure is a high entry barrier for the traditional game players, and limits the expansion of the ecosystem. But in KILLTHEZERO, anyone can play for free and gets an opportunity to earn a reward. You don’t need anything! All you have to do is to enjoy our game. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
