CELL 13 PRO v1.08 APK MOD starts out quite simple, as Chester guides you through CELL 1. However, you will quickly realise that not everything is so straight forward. You’re going to have to think outside the box to continue through the cells.
Use crates, balls, glass, elevators, laser bridges and most importantly portals. Individually these objects may not be useful. But together, with your creativity, you may find a solution to escape the cells.
