Iron Wake

One more run. That's the whole game.
Fight waves of medieval hordes in first person, with up to three friends. Between waves you spend your gold at the shop. After every boss you pick one of three relics that bend the rules. Wipe, unlock something permanent, queue it up again.

The loop
Enemies camp around the map and you choose which fight to pick. Dawdle too long and the pressure clock wakes everything at once, faster and angrier than it was a minute ago. Clear the wave, crack the chest, sort your loot, vote to push on. A boss every five waves. Kill three of them and you've won. Then Endless mode asks if you really meant it.

Gear worth fighting over (except you can't)
Every drop is yours alone. Your loot is invisible to your friends, so nobody races you to the corpse and the group stays a group. Rarity decides how many affixes an item rolls and how spicy the rolls get, and the ceiling climbs every wave, so wave 12 loot makes wave 2 loot look like a costume. Want to trade anyway? Drop it on the ground like a gentleman.

Vendors with questionable ethics
After each boss a stall opens: the Blacksmith rerolls your gear until it's what you wanted it to be, or the Alchemist sells elixirs and a Mystery Tonic that permanently changes a random stat with zero refunds. And sometimes, mid-run, a Gambler just wanders in from parts unknown. You can guess how his prices work.

Abilities, picked at the worst possible time
Leveling up heals you to full and hands you a pick-one-of-three ability choice the moment things calm down. Stack up to four actives, feed them all from the same stamina pool that runs your dodges and swings, and decide mid-horde whether you can afford to cast anything at all.

Co-op that respects your evening
1 to 4 players, friends-only invites, no matchmaking queue. It's free, so the hardest part of getting your group together is already solved. Downed friends can be picked back up. Clutch revives are the best thing in the game, and I will not be taking questions.

What's actually in it
A run you can win, an Endless mode for people who don't believe in endings, six enemy types plus elite variants, bosses, personal loot with real itemization, ability builds, and milestone unlocks between runs. It's small on purpose and free on purpose. Some of the jank is load-bearing. If it's not for you, the uninstall button costs the same as the install button did.
