Monster Collector is a single-player collection RPG focused on discovery and collecting.

Across 20 distinct regions, you'll encounter 1,020 monsters, including standard monsters, color variants, rare monsters, and ultra-rare creatures.

Battle them, record your discoveries, recruit them to your party, and keep searching for the ones you haven't found yet.

Rather than focusing only on becoming stronger, Monster Collector is about the satisfaction of discovering, collecting, and completing your catalogs.

Collect 1,020 Monsters

Travel through 20 distinct regions, including grasslands, forests, rivers, snowy fields, volcanoes, the deep sea, and otherworldly realms.

Your encounters, victories, recruits, drops, and other discoveries are recorded in the Monster Catalog. Search for monsters you haven't encountered yet, hunt down rare variants, and gradually work toward completing your collection.

Plan Your Next Hunt

There are many things to collect, including standard materials, rare materials, emblems, color variants, and recruitable monsters.

Choose the regions and equipment that best suit your goal, decide what you want to collect next, and plan your runs accordingly.

Recruit and Raise Your Monsters

Build a party of up to four monsters from the creatures you've recruited.

Manage your collection at the Ranch, where you can sort, search, and compare stats to find your favorites among the many monsters you've collected.
