OLAPU is a co-op action roguelite which you can play alone or together with a party of up to four people. Your goal is to survive the incoming enemy waves becoming more and more brutal as time goes on. If you manage to survive these waves you have proven yourself to be worthy of fighting the most powerful beings in this realm. These boss fights heavily resemble mechanics of raids in MMORPGs.

Before you start your adventure, choose the class that best represents you, support or damage dealer, ranged or melee. Each character has their own unique attacks and special abilities, allowing for a wide variety of play styles and opportunities for many different combinations of builds.

To stand any chance of surviving you must gear up, enemies will drop stars that you need to collect to level you and your fellow allies up. Stars can be exchanged for a piece of a constellation, which in turn can do simple things from increasing your base stats, to unlocking powerful summons to help you in your fight and everything in between.

Additionally, playing any given character levels them up based on your performance. Every fifth level, you’ll unlock a unique upgrade exclusive to that character, which will drastically aid you in future runs!
