Through Monday, May 25 we present The Other Side OSR Bundle featuring sourcebooks of magical witchery from The Other Side Publishing for Old School Revival systems like Shadowdark, Old-School Essentials, Swords & Wizardry, and other B/X-style Basic-era retroclones. Designed by Timothy Brannan, these bewitching supplements craft powerful character classes and hundreds of spells, monsters, and treasures for your old-school campaigns. Tim draws on classical and pagan sources to conjure ready-to-play backgrounds, heritages, familiars, cults and covens, invocations and curses, charms and talismans, house spirits, siren songs, places of power, and – of course! – brooms.

Although they reference historical occult traditions of deviltry and black magic (and, full disclosure, one back cover headline reads "EVIL!"), these high-crunch, nuts-and-bolts supplements from The Other Side aren't likely to revive the 1980s Satanic Panic. But the ritual powers in these books may evoke gasps from players and gamemasters alike: A Green Witch and a druid can awaken (animate) a forest; three Daughters of Darkness together can restore life to a vampire; three classical witches can summon a titan to destroy a city. Dozens of monsters, like bog crones, troll hags, demodands, flying heads, many types of lilim (children of Lilith), and the impundulu (lightning bird), present both immediate threats and adventure hooks. Call forth these figures from The Other Side to hold your gaming table spellbound.

Pay just US$7.95 to get all eleven complete old-school supplements in our Witchery Collection (retail value $64.50) as DRM-free .PDF ebooks, including The Left Hand Path, The Children of the Gods (and its spinoff book Cult of Diana), The Craft of the Wise, The Daughters of Darkness, The Green Witch, The Warlock, The Winter Witch, and the Shadowdark supplement The Witch: Book of Shadows, along with Monster Mash and Monster Mash II: A Midsummer Night's Dream, two books of playable werewolves, vampires, ghosts, golems, hobgoblins, bugbears, centaurs, and many other monstrous character classes.

Get this Other Side OSR offer before it starts the long journey into darkness Monday, May 25.

Through Monday, June 1 we present two offers featuring complete .PDF graphic albums of the Atomic Robo comic series from Tesladyne LLC, plus the 2014 Atomic Robo RPG from Evil Hat Productions. Start with the revived February 2021 Atomic Robo Bundle, then continue your Action Science research with its all-new companion, Atomic Robo New Era.

In 1923 Nikola Tesla unveils a robot with automatic intelligence: Atomic Robo! Granted full American citizenship in 1938 after a secret military operation, Robo founds Tesladyne, a two-fisted think tank that explores the fringes of scientific inquiry. After decades of high-octane, full-contact hypothesis testing at the edge of human knowledge, Robo and the Action Scientists of Tesladyne are the go-to defense force against the unexplained.

Created in 2007 by Brian Clevinger and Scott Wegener, Atomic Robo has been online since 2015 at atomic-robo.com. There's giant monsters, rogue agencies, underground cities, trans-dimensional vampires, one particularly annoying dinosaur, and explosions – lots of explosions. Atomic Robo reads like the Ghostbusters, Indiana Jones, Buckaroo Banzai, and Rocketeer movies crammed into a robot who wears pants.

[Note: These albums are presented as downloadable digital .PDFs, not hardcopies. Many of our offers are hosted on DriveThruRPG or DriveThruComics, but these Atomic Robo albums aren't available on DriveThru.]

1. ATOMIC ROBO [from Feb 2021]

If you're new to the series, this February 2021 Atomic Robo Bundle is an ideal starting point. Jump in anywhere – each graphic album in this offer is a self-contained story, so you can read them in any order.

Pay just US$12.95 to get all seven titles in this revived offer's Robo-Starter Collection (retail value $70) as DRM-free .PDF ebooks, including Evil Hat's complete 322-page Atomic Robo RPG rulebook based on Fate Core; three Atomic Robo graphic albums (Atomic Robo and Other Strangeness, The Ghost of Station X, and The Shadow From Beyond Time); Action Science resources like the Tesladyne Field Manual and FM-Ultra Field Manual; and behold the pulpy fruit of a vastly superior reptilian intelligence in Dr. Dinosaur's Time Travel Guide!

And if you pay more than the threshold (average) price, which is set at $24.95 to start, you'll level up and also get this revival's entire Robo-Bonus Collection with seven more titles worth an additional $68, including the Atomic Robo RPG supplement Majestic 12; four more Atomic Robo graphic albums (The Ring of Fire, The Savage Sword of Dr. Dinosaur, The Spectre of Tomorrow, and The Temple of Od); and two collections of the Robo companion comic Real Science Adventures: Flying She-Devils of the Pacific and The Nicodemus Job.

2. ATOMIC ROBO NEW ERA [all-new]

Though you can start almost anywhere with the Real Action Science adventures of Atomic Robo, you'll find it easiest to start with the nine albums above. Then move on to this all-new Atomic Robo New Era companion, with eight more albums of Robo's continuing adventures for an unbeatable bargain price.

Pay just $17.95 to get this offer's complete Robo-New Collection (retail value $80), including Agents of C.H.A.N.G.E., Dawn of a New Era, The Deadly Art of Science, Dogs of War, Fightin' Scientists of Tesladyne, Flying She-Devils of the Pacific, Knights of the Golden Circle, and The Vengeful Dead, along with three free Tesladyne LLC publications from the Atomic Robo creators: The Art and Process of Atomic Robo and Brian Clevinger's mini-RPGs 8-Bit Theater and Troubleshooter.

Science needs blood. Your blood! Join the prestigious and highly fatal ranks of the Action Scientists with this revived February 2021 Atomic Robo Bundle and its all-new companion, Atomic Robo New Era. Both offers end, though you'll probably survive, maybe, Monday, June 1.

Done with our travels – for now

This year's Traveller Week 2026 sequence of offers ends here – just ahead of May 1, known to many SFRPG fans as Traveller Day. The cover of the first Traveller boxed set (1977) featured Free Trader Beowulf's iconic call – the universal distress call m'aidez! (French "help me"), transliterated as "Mayday."

This week's offers, all featuring Mongoose Traveller Second Edition, included the December 2024 Mongoose Traveller Update Bundle (if you're new to the game, start here), Mercenaries (Dec 2023), Great Rift (Nov 2022), and the all-new Traveller Imperial Navy.

Traveller Week 2026 continues as, through Wednesday, May 13, we revive the December 2023 Traveller Mercenaries Bundle featuring soldier-for-hire supplements and adventures for Traveller Second Edition from Mongoose Publishing.

Mercenary has been part of the Traveller line since the 1978 Little Black Book 4. Mongoose published Mercenary 1E (2008) as the first supplement for its Traveller 1E. This revived Traveller Mercenaries offer presents the newest and largest version, the three-book Mercenary Second Edition boxed set (2021).

Funded in a February 2021 Kickstarter campaign (1,026 backers, £100K) and designed by longtime Traveller writer Martin J Dougherty, Mercenary 2E presents expanded systems for recruiting merc units of any size from squad to battalion; new mass-combat rules; defined equipment levels from Basic to Standard, Generous, Lavish, and Excessive; and a new ticketing system that lets you line up Commando, Striker, Warfighting, Cadre, Support, and Specialist contracts. A full support line adds tickets, equipment, adventures, and an entire theater of operations, the Solomani Front.

Note: These supplements and adventures require the Mongoose Traveller 2E rulebook, which isn't included in this offer. If you're new to the game, you want our revived December 2024 Mongoose Traveller Update Bundle in progress.

Pay just US$12.95 to get all three supplements in this revived offer's Player Collection (retail value $97) as DRM-free .PDF ebooks, including Mercenary, Mercenaries of Charted Space, and Field Catalogue.

And if you pay more than the threshold (average) price, which is set at $24.95 to start, you'll level up and also get this revival's entire Referee Collection with five more titles worth an additional $101, including Specialist Forces, Solomani Front, and three Mercenary Adventures: 1: Verloren Hoop, 2: Bug Hunt, and 3: Must Travel, Need Guns.

This revived December 2023 Traveller Mercenaries gets its ticket punched again Wednesday, May 13. (Note! This offer ends before the two offers we launched on the first day of Traveller Week – the revived December 2024 Mongoose Traveller Update Bundle and its all-new companion, Traveller Imperial Navy.)

The last week of April 2026 is Traveller Week at the Bundle of Holding – a sequence of five offers in four days, all featuring Traveller from Mongoose Publishing, that lead up to Traveller Day on Friday. Each year on May 1, fans celebrate Traveller Day in honor of the cover copy on the 1977 First Edition of Traveller: "This is Free Trader Beowulf, calling anyone... Mayday, Mayday..."

Through Monday, May 18 we kick off Traveller Week 2026 with two offers – one new, one revived. If you're new to Traveller, start with the resurrected December 2024 Mongoose Traveller Update Bundle, with the core rulebook and useful supplements. Then check its all-new companion, Traveller Imperial Navy, with sourcebooks and adventures that focus on the Third Imperium space fleet.

Traveller is a game of bold explorers and brave adventurers. Spaceports, ancient civilizations, air/rafts, cold steel blades, laser carbines, far distant worlds, and exotic alien beasts – this is the futuristic universe of Traveller, the original and classic science fiction roleplaying game. Whether you're a newly mustered recruit or a six-term veteran, you'll find much to explore in these Traveller revivals.

1. TRAVELLER UPDATE [from Dec 2024]

Mongoose Traveller lets you explore the universe the way it suits you. Lightly revised to incorporate tweaks, rules updates, and new art, the Traveller Core Rulebook Update 2022 contains everything you need to create your Traveller and begin exploring the galaxy in the far future. And the supplements in this revived December 2024 Mongoose Traveller Update Bundle give you new allies, contacts, and enemies – starships large and small – and robots of every size from nano to colossal.

Pay just US$17.95 to get all five titles in this revived offer's Traveller Updates collection (retail value $150) as DRM-free .PDF ebooks, including the complete Traveller Core Rulebook Update 2022, Traveller Companion Update 2024, Adventure Class Ships, Small Craft Catalogue, and the Robot Handbook.

2. TRAVELLER IMPERIAL NAVY [all-new]

This all-new Traveller Imperial Navy companion offer adds sourcebooks and adventures about the Third Imperium space fleet. The Imperial Navy and the other titles in this new offer display the greatest military force in the Third Imperium, from the great fleets down to a band of new recruits. The navy is entwined in the politics and economics of the Imperium. It's a training ground for the great nobility, and, for the general populace, a route to social advancement. Without its senior service, the Third Imperium would not exist.

Pay just $14.95 to get all six titles in this offer's Imperial Navy Collection (retail value $115), including The Imperial Navy sourcebook, Element Class Cruisers: Ship Builder's Blueprints (plus the Naval Campaigns Handbook), and all four Naval Adventures: 1: Shakedown Cruise, 2: Showing the Sunburst, 3: Fire on the Sindalian Main, and 4: Enemy of My Enemy.
