Insaniquarium is a game where you feed fish. And fight aliens. And feed fish to other fish. And avoid electrocution. By now you either think this game is pointless or endlessly addictive. And if you think that sounds addictive you're not alone, since this game was downloaded 20 million times in five years.

Insaniquarium was later re-released in an enhanced version dubbed Insaniquarium Deluxe, which is the version you can still get off of Steam to this day, and the version that Insaniquarium Portable uses.

Total Annihilation is an RTS game with a cult following. Whereas other games in the genre focused on resource scarcity or micromanagement of units, it focused on resource streaming and large scale battles across bigger maps.

The game's designer, Chris Taylor, would go on to make spiritual sequels in the form of Supreme Commander amd Planetary Annihilation.

Developer: Bungie West
Release Date: 29 January 2001

The last game Bungie made before being absorbed by Microsoft and consumed with Halo, Oni is that game I barely remember but folks on my Discord desperately love. It's also never been released on digital distribution services, has been out of print for ages, and was the only product of the Bungie West offshoot.

Still, it is the subject of multiple reverse engineering attempts, the latest of which recreates the game for Apple Silicon.
In the anime-style game you play as a female protagonist aligned with the police force but learns that elements of her past are being hid from her, causing a quest of self-discovery.

Are you tired of waiting five years for a new game, only to have it cost even more than last time and then the developers get laid off by a heartless corporation? Well then do I have a deal for you.

BRAZILIAN DRUG DEALER BEFORE 4 is the sequel to BRAZILIAN DRUG DEALER 3, and judging from the title your business from the first game isn't finished, and now you have to save someone from a soccer star. Or a clown. I'm not sure.

I've mentioned it before but back in the day, you had game developers which could take a handful of people, make a game on a small budget, turn a profit, and then crank out am upgraded sequel in a year. Well, Joeveno and NoQuarter are doing that again. Literally - the release dates of 3 and 4 are almost one year apart to the day. And BRAZILIAN DRUG DEALER BEFORE 4 features updates like double jumping, dash moves, and a new UI.

I love AAA gaming like everyone else but I miss the good old days when gaming was more fast and furious, so I'm a big fan of these guys now, and not just because I got to hang out with them at QuakeCon 2026. As a bonus, this is not only the newest game on Mac Source Ports (as of this writing) but it's the first time we've been able to add a Mac build of a game on release date.

So, first things first: this is the 2006 game called Prey, not the more recent 2017 game called Prey.

In keeping with the trend of melding the game source with a related engine source in order to play a commercially unavailable game, here's Prey, 2006 edition.

The brief history is that in the late 90's 3D Realms tossed their hat into the "cool tech with one word name" game with a game and engine called Prey. It had deformable terrain, portals, and a Native American protagonist. Ultimately though it is never finished or released. Years later, while develping Duke Nukem Forever they dust off the old concept and hand it to Human Head Studios. They use id Tech 4 (so, the DOOM 3 engine) to make the game, keeping the protagonist and the portals (and even shipping before Portal) but swapping out the deformable terrain for gravity defying sections.

Years later 3DR sold the IP to ZeniMax, who was having Human Head make a Prey 2, reportedly tangentially connected to the first game, but it eventually gets canceled. In 2017 they decided to attach the Prey name to Arkane Studios' otherwise unrelated System Shock homage project.

The game has been unlisted and unavailable for years now in a situation similar to NOLF 2 where the rights are ambiguous due to corporate shenanigans but if you have it, now you can play it on your Mac. Again.

Pro tip: if you have a physical copy you can still activate the CD Key on Steam and activate this otherwise unavailable title.

Long before the franchise became known for the MMO, the Warcraft series started out as a series of real-time strategy games. The original game was a hit, following the conventions of the then relatively new genre, but Warcraft II: Tides of Darkness upped the ante in that golden age where a sequel could follow a year later and be radically improved.

In Warcraft II you choose a side, Orcs or Humans, and collect resources to build an army to destroy the other side. The game introduced several mechanics and interface decisions that would become standard conventions.

Note that the source ports featured here need the original versions of the game, not the later Remastered versions.

I may have overused the term Cult Classic on this site, but this game goes one step further: it's one of gaming's Holy Grails.

No One Lives Forever 2: A Spy in H.A.R.M.'s Way is the second entry in the NOLF series. You play as Cate Archer, a spy for U.N.I.T.Y., a British counter-terrorism group fighting the H.A.R.M. organization. Basically it's a parody/homage to the James Bond movies of the 1960's with a stylish, groovy protagonist. The game was critically well recieved and is beloved within gaming fandom.

So why is it a White Whale? Because it has been commercially unavilable for many years now. It's a bizarre situaiton where the companies involved with making the games have been bought and sold and absorbed enough times that no one knows who owns the rights. The parties involve are willing to spend the effort to quash efforts from GOG and Night Dive to reissue the game but not enough to actually hash out the rights.

So consequently it was absolutely not on my Bingo card for this year that someone would figure out how to run the game on Apple Silicon. So if you fall in the Venn Diagram of people who want to play this game and are willing to figure out how to get the data on your Mac, prepare yourself for one of the best games money can't buy, though not for lack of trying.

FLESHCANCER is a horor-themed Boomer Shooter from Brazil, published by the same team as BRAZILIAN DRUG DEALER 3. You take the role of someone who seeks to stop the rise of an evil cult that formed in the aftermath of the 1985 fall of the military dictatorship.

The game is currently in Early Access with one of the planned episodes released, and like BRAZILIAN DRUG DEALER 3 uses the Quake engine and features impressive level design.

In the annals of classic and retro gaming, Infocom's rise and fall is one of the most documented and well followed, with books and documentaries on the subject. Their downfall was due to a number of factors, including an ill advised attempt to break into the database market, but also because by design the nature of their text-based Interactive Fiction games became dated once computers got better at graphics.

Zork Zero was their attempt to bridge the gap. It's also one of their last games. It's also a prequel to the other games, and until recently Splatterlight didn't support it. Custom support was rolled into the latest version so now it's easy to experience the game so fire it up and imagine an alternate universe where it was successful Infocom went on for decades.

In hindsight, one of the ironies of DOOM, famous today for running on everything, is that the consoles of the era couldn't run it well, usually in the form of the game having to make compromises on quality or content in order to work. The version for the origina PlayStation was no different, though at the time it was the best attempt yet.

Williams Entertainment (now Midway Games) did a good job making it run on Sony's console, and for bonus points it incorporated a custom campaign featuring levels from both DOOM and DOOM II.

Similar to the BurgerDoom project, PsyDoom is not an attempt to simulate the PSX version, it actually uses the disc image for the PSX version of the game. You can choose to either run the PSX version of the levels with modern quality of life improvements or you can have it recreate the experience of running in a period-accurate resolution and framerate.
