Koop Packmates PC

Packmates: Your Backpack is your Build

You have a backpack. Good. You’re going to need it.

Packmates is a survivor roguelite about turning inventory management into a weapon. The monsters brought claws, spells, ghosts, and slime royalty. You brought a bag full of junk and a dangerous willingness to sort it properly.

Backpack Inventory System

Every run starts with a backpack, a handful of items, and the false belief that this will stay manageable. It will not. You will be stuffing weapons beside trinkets, and armor into whatever corners remain while trying to squeeze every last adjacency effect out of the layout.

Need more room? Get a Pocket. Place it on a locked inventory slot to unlock it. Congratulations. Your organizational problem is now larger and somehow worse.

The right arrangement turns a decent build into a disaster for everything on screen. The wrong arrangement turns your backpack into an expensive grave marker.

Item Leveling and Infusion

Power does not come from items and their synergies alone, it also comes from upgrading what you already have. Forge matching items together to increase item level and carry them deeper into your run.

Then utilize Infusion to merge items with Trinkets, transferring powerful adjacency effects onto the item.

With item leveling and infusion, you'll get gear that does more, hits harder, and opens up new layouts that were not possible on the previous Floor.

Gamemodes: Standard and Endless Adventure

Standard Adventure — Fight through 3 Acts, defeating elite enemies & bosses to earn Hero Gems which you can spend on permanent hero upgrades.

Endless Adventure — Keep looping through the Acts as long as you can stay alive. Enemies get harder and faster, and you're now rewarded with Legendary Shards for unlocking powerful Legendary items.

Objectives — Head to objectives on each floor to find extra fights that ask more of your build. Objectives provide additional rewards, giving you more reason to push beyond surviving the floor. If you want bigger rewards, you’ll have to earn them.

Boss Fights

Every Act ends with a boss, and every boss asks different questions of your build. Bring enough damage to dethrone the Slime Queen in Act 1. Survive the split pressure of Frost and Ignis in Act 2. Make it to Act 3 and bring down the final boss before your adventure comes to an end.

Boss levels are where weak layouts get exposed and strong ones get a chance to show off.

Unlockable Heroes, Classes, Progression Trees, and Legendary Items

Winning a run is nice. Building for a future of stronger runs is nicer.

Relics are equipped before you start your adventure and change the rules of the run. Boon Relics make things easier. Curse Relics make things more difficult. Naturally, you will eventually equip the dangerous curses on purpose because that’s where the interesting stories live.
