Codename Ocean Keeper
(Like and sharing game for your friends)
Codename Ocean Keeper drops you into a crashed spaceship on a hostile ocean planet, and every run is a fight to drill deeper, upgrade faster, and survive the next wave of underwater monsters. It's a top-down mining roguelike shooter from developer psp where you play as a Miner whose ship is wrecked, surrounded by abyssal fauna that would rather keep their resources to themselves. The loop is simple to learn and hard to put down: mine, loot, upgrade, defend, repeat.
This page covers what the game actually does, how the update package is packaged, and the practical details you need before you download. The package listed here includes the base game plus Update 1.05, which is labeled as fixing firmware compatibility across 5.05, 6.72, 7.02, 7.55, 9.00, and 11.00+ console revisions. If you're running a specific firmware, that line matters more than any marketing bullet.

What You Actually Do in Ocean Keeper
The premise sets the tone: your spaceship has crashed on a planet covered in water, and the local wildlife is not friendly. You control a diver who moves between two modes of play. In the mining phase, you drill through caves looking for resources and artifacts that fund your upgrades. In the combat phase, the same caves turn into a battlefield as monsters swarm in. The game asks you to decide when to keep drilling and when to bail out and switch to dynamic combat mode, because the fauna react badly to you stripping their resource nodes.
Between attacks, you spend what you've gathered. That means powering up your diver, your mech, or your weapon, or spending the downtime exploring a new dungeon for better loot. The upgrade economy is the heart of the roguelike structure here, and the choices you make between waves determine whether the next assault is survivable.
Mech Spider and Automated Defense
Your Mech Spider is the mobile platform you invest in, and it's also a target for upgrades alongside your weapons and diver skills. You can build automatic turrets to cover your mining operations and send out drones to collect loot while you focus elsewhere. That layered defense setup rewards planning: turrets and drones buy you time, and time is what you need to reach the next resource pocket.
Biomes and Exploration
The underwater world is split into many biomes, and the game pushes you to travel across locations in search of the remains of a lost civilization. The environments range from abandoned sci-fi laboratories to mines packed with artifacts. Each biome changes what you're drilling for and what's hunting you, which keeps a run from settling into a single rhythm.
Boss Fights and Replayability
Boss encounters are built as large-scale set pieces, and the roster includes creatures like a giant crab and a flying mouse. The developers have held back details on the full list, which suggests the boss count is meant to be discovered rather than spoiled. Each new session rearranges the underwater world's secrets, monster waves grow harder, and meta upgrades plus different Mech types give you new ways to approach the same fight. If you enjoy roguelikes that lean on meta progression between runs, this structure will feel familiar. Fans of keeper-themed titles might also enjoy Ages of Mages The Last Keeper, which shares the genre label but takes a very different combat approach.
Key Features
- Top-down mining roguelike shooter with a split loop between resource drilling and wave defense
- Playable Miner character with diver, mech, and weapon upgrade paths
- Mech Spider platform that you can upgrade across runs
- Automatic turrets and loot-collecting drones for hands-off defense support
- Multiple biomes, including abandoned sci-fi laboratories and artifact mines
- Large-scale boss battles against unique creatures like a giant crab and a flying mouse
- Meta upgrades and multiple Mech types that carry between sessions
- Fifteen supported screen languages, including English, Japanese, Korean, and Brazilian Portuguese
- Update 1.05 included, with firmware compatibility fixes for 5.05, 6.72, 7.02, 7.55, 9.00, and 11.00+
Pros & Cons
- Pros: The mining-and-defense split gives each run two distinct phases instead of one repeated loop. Upgrade choices feel meaningful because they apply to three separate systems. Biome variety keeps exploration from feeling flat. The included 1.05 update addresses firmware compatibility across a wide range of console revisions.
- Cons: The published file size is small at 2MB, which is unusual for a modern action title and worth verifying against your expected install size before you commit. The listed operating systems are Windows and iOS even though the release is described as a PS5 title, so confirm the package matches your platform. Boss and enemy variety is described in broad terms, so you won't know the full roster until you play.

Version Freshness and Publisher Details
Update 1.05 is the current package on this listing, and its stated purpose is fixing compatibility across firmware versions 5.05, 6.72, 7.02, 7.55, 9.00, and 11.00+. If you're on one of those revisions, installing the updated package rather than an older base build is the practical choice. The publisher credited on this release is psp, the same account that posts the archive password in the comments, which is the standard pattern for this catalog.
Credit for the release goes to zecoixao and Viki per the package notes. There is no claim of malware scanning or verified clean status attached to this listing, so treat the archive with the same caution you'd apply to any third-party download: check the file after extraction, and don't run anything you didn't expect to find inside. If you need help with the extraction process, the linked guide download and tool download pages cover the steps.
Who This Is For
Ocean Keeper suits players who like roguelikes where the downtime between fights is as important as the fights themselves. If you enjoy planning an upgrade path, juggling turret placement, and deciding when to abandon a mining run before the monsters overwhelm you, the loop will land. It's less suited to players who want a pure twin-stick shooter with no resource management, since drilling and looting take up a real share of each session. The top-down perspective and wave-based structure also mean the challenge scales with your willingness to experiment with different Mech types and meta upgrades.
If you're browsing for more retro or arcade-flavored action to pair with it, Codename Kids Next Door Operation VIDEOGAME sits in a completely different era and style, and Baku Baku Animal World Zookeeper Contest offers a puzzle-battle alternative when you want a break from drilling.
Practical Notes Before You Install
Extract the archive with the password [DLPSGAME.COM] before doing anything else. Confirm the update is present alongside the base game files, since the 1.05 patch is the part that carries the firmware fixes. If your console firmware falls outside the listed range, the package may not behave as described, and the release notes don't cover revisions beyond 11.00+. Keep the extracted folder intact until you've confirmed the install completes, so you don't have to re-download the 2MB archive from a mirror.
Language settings are handled at the screen level, so you can switch between the fifteen supported languages without a separate language pack. That's useful if you prefer Japanese or Korean voice-adjacent text while keeping the interface in English.
