Steam has added six more games you can download and keep at no cost, according to a roundup published on October 29, 2026. The batch covers an idle MMORPG, a cow platformer, a shop sorting game, a comedy horror shift, a horde survival roguelike, and a cryptid card battler.

All six are listed as free to play on Steam. That means the download itself costs nothing, though some titles include optional in-game purchases or, in one case, an Early Access label. Check each store page before you install, because free to play and free forever are not always the same thing.

6 free Steam games in the October 29 batch

The six games in this batch are Mimic2, MoooooN, Lost & Found, Evenin' Shift, The Loer Chronicles, and Portentum. Screen Rant's October 29 roundup presents them as new free additions with no purchase needed to download, and Steam's own pages list Mimic2, MoooooN, Lost & Found, The Loer Chronicles, and Portentum as free to play. Evenin' Shift is the one entry where a direct Steam store price page could not be confirmed during research, so treat its listing as reported in the roundup rather than checked on the store page itself.

Mimic2: idle MMORPG battles that run while you are away

Mimic2 is an idle and AFK MMORPG on Steam in which map battles run fully offline on the server, even when your PC is off. You start with a few hundred thousand damage, farm the easiest map, claim battle rewards, kill bosses, and spend loot on upgrades that let you farm faster or move to stronger maps. The store page lists 40 bosses across 6 elemental types, 95 item slots, 7,515 total item levels, 9 maps with 35 difficulty tiers, and 832 quests.

The appeal here is low pressure. Boss fights, upgrades, enchants, and the market need your attention, but the map grind does not demand that you sit at the keyboard. The developer also states there is no item shop and no pay-to-win design on its official site, and the Steam page notes that map battles continue while your PC is off. That makes Mimic2 a reasonable second game: something ticking over in the background while you play something else.

The Mimic2 store page also discloses that its 2D art was made with generative AI tools and then selected, edited, and assembled by hand, with no AI-generated content produced while the game runs.

MoooooN: a cow platformer with one very high goal

MoooooN is a casual 3D platformer in which you play as Cow, a cow who has always wanted to jump over the moon. Friends have built a course meant to end with Cow heading to the stars, and the run takes you through levels, conversations with animal characters, and movement upgrades found around each level. Steam lists it as free to play, with a release date of October 9, 2026, and 4 levels to explore.

The store page keeps the pitch short: simple and fluid 3D movement, quests from NPCs, songs and characters based on nursery rhymes, and a game that can be finished in an afternoon before going back for achievements. Steam user reviews at the time of checking were positive across 23 reviews.

Lost & Found: match the item, find the owner

Lost & Found is a first-person fantasy shop game where you run a busy Lost & Found guild and decide whether the person in front of you is the true owner of an item. Customers arrive with stories, items carry descriptions, receipts, notes, photographs, and markings, and a wrong handover can cost you reputation. The store page describes 50 days of growing chaos, with more customers, harder clues, and decoys as the days pass.

The sorting comes from the work itself: organise items on shelves, deal with unclaimed belongings, track what has passed through the shop, earn gold, and upgrade your workspace and storage. Screen Rant describes it as a relaxing sorting game with solo and multiplayer modes and a Very Positive Steam rating, but the Steam store description checked for this article centres on the single-player shop loop, so treat the multiplayer detail as reported, not confirmed on the store page.

Evenin' Shift: a comedy horror shift in early-90s Somerset

Evenin' Shift is a comedy horror game set in Somerset in which you play Jack, a security officer on a night shift that looks quiet at first. The job is simple on paper: let the right people in, send the wrong ones away, and try not to make enemies. Strange visitors turn that simple gate job into a series of judgment calls, and the wrong call is where the horror creeps in.

This is the Halloween pick of the batch. It is also the entry to handle with the most care: the premise, setting, and Jack's gatekeeper role are confirmed by the Screen Rant roundup and an independent game listing, but no direct Steam store page with a confirmed free price was found during research. If you cannot find it listed as free on Steam when you search, do not assume the roundup alone settles it.

The Loer Chronicles: steer only, and watch your elements

The Loer Chronicles is a free horde survival game in which skills fire automatically, so your job is to move, dodge, and pick the next upgrade. The store page lists 5 Elementalists, 35 element skills, 35 chain skills, 60 masteries, 96 relics, 15 realms, and 15 Elemental Lords. Stage runs stay short: hit the kill quota, then face the Elemental Lord within 120 seconds.

Elements decide everything. The right pairing deals about double damage, while the wrong pairing deals nothing and heals the target for roughly twice the hit, according to the Steam page. The game needs an internet connection and a Rainlight Studio account, and it has no ads on PC and no energy system, with shop items also earnable in play.

Portentum: cryptids, cards, and broken combos

Portentum is a deck-building auto battler that entered Steam Early Access on October 28, 2026, and it is free to play during Early Access with plans to stay free after, according to the developer. You build a deck of 30 cryptids and mushrooms, spend coins to field a five-slot warband, and then watch battles play out on their own. Win 10 rounds to win a run; lose 5 and you are out.

The roster pulls from folklore around the world: Bigfoot, Mothman, Nessie, the Chupacabra, the Yeti, the Jersey Devil, and a raccoon named Jimothy. Each cryptid has its own ability, from damage and healing to summoning minions and bending dice, and battles are fought against snapshots of other players' warbands rather than bots. As an Early Access game, balance and content will shift, so expect rough edges.

How to claim these free Steam games

Search each title on Steam, open its store page, and confirm it still shows as free to play before you install. Free to play listings can include optional purchases, and Early Access titles such as Portentum can change price plans, even when the developer currently says it plans to stay free. If a title shows a price instead of free to play on your regional store page, that page wins over any roundup.

Is this batch worth downloading?

Yes, with one distinction. MoooooN, The Loer Chronicles, and Portentum have the clearest store pages and the most distinct hooks, so they are the safest first downloads. Mimic2 suits players who want long-term idle progress without daily pressure. Lost & Found suits players who like slow deduction and shop management. Evenin' Shift is worth a look for Halloween, but verify its Steam listing first, since its free status rests on the roundup rather than a confirmed store page check.

None of these six replaces a big paid release, and none needs to. They fill different gaps: a background game, a short platformer, a quiet deduction game, a seasonal horror shift, a build-crafting survival loop, and a card battler built for testing combos. Pick two, try them for an evening, and drop the ones that do not hold up.

FAQ

Are all six games really free on Steam?

Five are confirmed as free to play on their Steam store pages: Mimic2, MoooooN, Lost & Found, The Loer Chronicles, and Portentum. Evenin' Shift appears in the October 29 free batch roundup, but a direct Steam store price page could not be confirmed during research, so check its listing before installing.

Do free to play games stay in my library?

Free to play games stay tied to your Steam account once added, but they can include optional in-game purchases, and Early Access games can change over time. The download costs nothing; extras inside the game may not.

Which game should I try first?

Try MoooooN first for a short, finished-feeling session, The Loer Chronicles for a systems-driven survival loop, or Portentum if you like building card decks and testing combos against other players' warbands.

Is Portentum finished?

No. Portentum is in Steam Early Access, launched October 28, 2026, with an aim to leave Early Access by the end of 2027. The core game and three modes are playable now, but balance and content will change.

Does Mimic2 need my PC left on?

No. Mimic2's map battles run on the server while your PC is off, according to its Steam page. Boss fights, upgrades, and market actions still need you to play actively.
