Seven sharp, wildly different boomer shooters, one limited‑time bundle. Here’s what makes Selaco, CULTIC, I Am Your Beast, MULLET MADJACK and Boltgun stand out, plus what PC, Linux and Steam Deck players should know before buying.
If you have even a passing interest in 90s‑style shooters, Digiphile’s Boomer Shooter Blueprint bundle is about as clean a sampler platter as you could hope for. Curated by YouTuber Kirk Collects and sold on Digiphile, the new storefront from ex‑Humble staff, it pulls together seven recent retro‑leaning FPS games that all push the formula in different directions.
For $17 you get Steam keys for Selaco, CULTIC, Warhammer 40,000: Boltgun, I Am Your Beast, MULLET MADJACK, Beyond Citadel and Incision, with a charity add‑on tier that throws in several soundtracks and an artbook. None of the games have been in a big curated bundle before, which makes this feel more like a genuine discovery pack than a clearance sale.
From a buyer’s perspective there are a few practical hooks. All titles are redeemed on Steam, so you get its cloud saves and Proton support. Linux and Steam Deck owners are particularly well served: Selaco is native on Linux, CULTIC and MULLET MADJACK both run well through Proton according to early Steam Deck reports, Boltgun is a known good Deck performer, and the rest of the lineup has been tested and covered positively by Linux‑focused sites. There is no custom launcher or account to juggle beyond Digiphile’s store login and Steam itself.
The bundle is available directly from Digiphile and, according to Noisy Pixel and other outlets, runs from February 24, 2026 at 9 AM PT through March 10, 2026 at 6 PM PT, or while keys last. That gives you a couple of weeks to decide if this is the right crash course in boomer shooters for you.
Selaco: GZDoom wizardry with immersive‑sim flavor
Selaco is the headliner for a reason. Built on GZDoom but miles beyond the usual mod pack, it blends chunky pixelated gunplay with modern level scripting and a surprisingly grounded sci‑fi story about a refugee colony under siege.
What makes it special in the boomer shooter space is how tactile everything feels. Destructible environments let you chip chunks out of cover and shred office furniture with shotgun blasts. Enemies coordinate, flank and react to noise, so fights feel more like controlled chaos than simple circle‑strafing. There is a distinct immersive‑sim streak too, with logs to read, side routes to uncover and environmental clues that reward paying attention instead of sprinting straight to the exit.
On the technical side, Selaco is one of the most Linux‑friendly games in the bundle. It ships with native Linux support and runs smoothly on Steam Deck with sensible default settings, helped by its efficient engine and sensible scalability. If you are grabbing the bundle primarily to play on Deck or a Linux desktop, Selaco alone easily justifies the asking price.
CULTIC: Slow horror, fast guns
CULTIC channels the grimiest side of 90s shooters. Think grainy low‑res textures, thick atmosphere and a lot of dynamite. You play a lone cop mowing through a fanatical cult, lobbing explosives into clusters of robed enemies and sliding between cover to avoid their rifle fire.
Instead of pure speed, CULTIC emphasizes spacing, positioning and tool use. Enemies hit hard and often outnumber you, but you have physics‑driven props, throwable weapons and a very generous slide that lets you reposition mid‑fight. Chapters are built as small sandboxes with multiple angles of attack, which encourages replaying encounters to find cleaner or flashier solutions.
CULTIC is Windows‑only on paper, yet it fares well on Linux and Steam Deck through Proton, helped by modest system requirements and a focus on single‑player content without intrusive anti‑cheat. Deck players may want to cap the frame rate and tweak resolution scaling for longer battery life, but from a compatibility angle it is one of the safer picks in the bundle.
I Am Your Beast: Covert revenge thriller in FPS clothing
Where most boomer shooters lean into arenas and keycards, I Am Your Beast feels closer to a playable revenge thriller. You are a black‑ops legend forced into retirement who finds himself hunted through the North American wilderness, then methodically dismantles the people who ordered the hit.
Each level plays out like a compressed stealth‑action vignette, with tight, readable layouts and a focus on first‑shot lethality. You can go loud and lean into the tactile recoil and chunky hit reactions, but the game really shines when you plan your approach, breach a room and clear it in seconds without giving enemies time to respond. It is a refreshing twist on the boomer shooter template, keeping the snappy movement and quick restarts while borrowing pacing and tone from thrillers.
On PC it runs through Steam with no extra launcher. There is no native Linux port right now, but compatibility reports via Proton have been positive, helped by its relatively simple tech stack and short mission structure. On Steam Deck, the compact levels are a good fit for portable pick‑up‑and‑play sessions.
MULLET MADJACK: Time‑attack anime chaos
MULLET MADJACK is what happens when you throw boomer shooter gunfeel into a blender with arcade score chasing and 90s anime VHS energy. Every stage is a vertical rush where your life ticks down constantly. The only way to stay alive is to keep killing, chaining headshots and melee finishers to top up your timer as you climb toward the next elevator.
There is almost no downtime. Levels are constructed as bite‑sized combat puzzles that last a minute or two once mastered, filled with shortcuts, destructible walls and hidden routes. You are encouraged to replay them until you find the most stylish, efficient line, then chase S‑ranks and leaderboard times. It uses retro FPS fundamentals but dials the pacing and visual flair up to something closer to a rhythm game.
From a platform standpoint, MULLET MADJACK is another straightforward Steam title that behaves well under Proton and has already earned praise from Steam Deck‑focused sites. Its minimalist menus and short bursts of play make it particularly friendly for handheld sessions, and there is no DRM beyond Steam itself.
Warhammer 40,000: Boltgun: The bolter finally feels right
Boltgun takes one of Warhammer 40K’s most iconic weapons and finally makes it feel as brutal as the lore always claimed. You play an Ultramarine in a 2.5D, sprite‑driven shooter filled with heretics and daemons, hammering the trigger on a bolter that sounds and feels like hurling explosive bricks.
Design‑wise it is probably the most straightforward boomer shooter in the bundle, but that clarity is its strength. Wide arenas, chunky enemies, color‑coded pickups and aggressive movement create an almost meditative loop of sprint, swap weapons, delete a horde, repeat. The visual style walks a neat line between pixel art and the heavy metal cover aesthetic you expect from 40K.
Boltgun has been a known success story on Steam Deck for a while, with official Verified status in many regions and stable performance with Proton. That, plus a lack of launcher baggage compared to some other 40K titles, makes it a safe recommendation for handheld and Linux players who want something pick‑up‑and‑play that still has a full campaign’s worth of content.
How the rest of the bundle fits together
Beyond Citadel and Incision round out the lineup and help show just how broad the “boomer shooter” label has become. Beyond Citadel leans on tight arenas, combo‑driven scoring and wild mobility, while Incision embraces bleak industrial horror, dense level layouts and punishing combat that demands methodical play.
Taken together with Selaco, CULTIC, I Am Your Beast, MULLET MADJACK and Boltgun, the bundle effectively functions as a curated tour of modern retro shooters. You get story‑driven sci‑fi, chunky horror, score‑attack arcade action and a licensed throwback that lands the fantasy of a legendary weapon, all selected by people who clearly care about the genre.
DRM, Linux and Deck: What you need to know before buying
Every game in Digiphile’s Boomer Shooter Blueprint bundle comes as a Steam key. There is no separate client to install, and once redeemed the games sit in your Steam library like any other purchase. Steam’s own DRM layer applies, but there is no extra online check beyond what Valve already uses.
For Linux and Steam Deck users, this is one of the more welcoming big bundles in recent memory. Selaco ships with a Linux build. CULTIC, Boltgun, MULLET MADJACK, I Am Your Beast, Beyond Citadel and Incision all run via Proton, with multiple outlets reporting good experiences and Steam Deck‑focused sites highlighting several of them as particularly strong handheld picks. None of the included games rely on invasive anti‑cheat or kernel‑level drivers that typically break Proton.
If you are building or already running a Linux gaming setup, that makes the $17 asking price easier to justify. You are not buying a pile of Windows‑locked curios; you are getting a set of shooters that either work out of the box or need only light tweaking.
Is the Boomer Shooter Blueprint bundle worth it?
From a pure value perspective, seven well‑regarded FPS games for $17, all relatively recent and none previously bundled in a curated pack, is an easy sell if you like retro shooters at all. As a discovery tool, it is even better. Selaco alone can carry a full campaign’s worth of playtime, CULTIC and Boltgun both have strong followings, and MULLET MADJACK plus I Am Your Beast offer radically different spins on speed and structure.
More importantly, the bundle is thoughtfully assembled. Instead of seven near‑identical Doomlikes, you get a spectrum of design philosophies that chart where the boomer shooter genre has gone over the last few years. With a limited window to buy and a generous level of Linux and Deck friendliness, Digiphile’s Boomer Shooter Blueprint is one of the rare bundles that feels like a curated crash course rather than a backlog trap.
