The bold and futile attempt to fix the disastrous Aliens: Colonial Marines

2025-10-11 16:00 UTC · PC Gamer · Rick Lane

Aliens: Colonial Marines is one of the most infamous misfires of gaming history, a disaster of a scale that's relatively rare in the upper echelons of game development. Virtually everyone who played it at the time acknowledged that it was a buggy, broken, unfinished mess, and there were rumblings that Gearbox outsourced large portions of the game's development while it focused on building Borderlands 2...

Alien Day Steam sale drops prices on some real highs and lows

2023-04-21 19:55 UTC · PCGamesN · editor@pcgamesn.com

Alien Isolation is an incredible example of how to perfectly capture the vibe of a beloved movie series and transform it into one of the best horror games in years. As Alien Day 2023 approaches, a celebratory Steam sale offers a big discount on Alien Isolation, along with similar deals on other hits, as well as some less-successful takes on the beloved space horror franchise.

Meet the modder who's spent years trying to fix the "unfixable" Aliens Colonial Marines

2019-01-24 12:00 UTC · Eurogamer

2013's Aliens: Colonial Marines is one of the most memorable gaming disappointments we've ever seen. After witnessing a gorgeous, atmospheric engine showcase back in 2011, fans of the series were hungrily awaiting a true sequel to the iconic 1986 film. But then, in February 2013, Aliens Colonial Marines came out and the horror of its truth became reality. Gearbox's first-person shooter was an infestation worthy of being nuked from orbit. The AI was broken, the gunplay was unreliable, and the "perfect organism" - the Aliens themselves - couldn't even run at the player properly. Meanwhile, down

Gearbox legal battle with former employee becomes messy publicly

2019-01-12 14:00 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Jay Castello)

Back in November, the Borderlands and Aliens: Colonial Marines studio Gearbox Software filed a suit against their former lawyer, Wade Callender, accusing him of “exploit Gearbox s generosity and trust for his own personal gain.” The suit was not particularly interesting, alleging that Callender did not fully pay back a loan he borrowed to secure his house, and that he used a business credit card for personal expenses. Then, last month, Callender counter-sued, accusing Gearbox CEO Randy Pitchford of “siphoning” a $12 million ( 9.34m) “secretive ‘Executive Bon

Gearbox is seeking a 'Programming Copy Editor' to frag future typos

2018-07-17 17:18 UTC · PC Gamer

Aliens: Colonial Marines suffered from a lot of issues, including wonky enemy AI that resulted in erratic and confused Xenomorph behavior. More than five years after it came out, someone discovered that the bad behavior could have been the result of a simple typo in the code—a theory that we put to the test and found to be at least partially correct. Launching without that typo probably wouldn't have been enough to "save" the game but it sure would've helped, and so to ensure that something like this doesn't happen again, Gearbox has posted a job listing for a P

A single typo wrecked Aliens: Colonial Marines and people are handling it fine

2018-07-14 21:19 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Brock Wilbur)

In what feels like The Games Story Of The Year, during the Steam summer sale the much reviled Gearbox title Aliens: Colonial Marines was marked down to a stupidly low three dollars. A modder happened to notice that in the INI file for the game, there is a single typo that is — get this — responsible for many of the awful AI choices that the xenomorphs make in the game… like running directly at you on their hind legs instead of crawling on the walls and using ducts to surprise you. A once horribly broken game is now… functioning? Thanks to a single letter? Sure. That&#82

All this time, Aliens: Colonial Marines' stupid AI may have been caused by a single typo

2018-07-14 00:32 UTC · PC Gamer

Aliens: Colonial Marines released on February 11, 2013. It wasn't very good. As Chris Thursten noted in our review, the AI of the aliens was especially bad. At the time, he said, "aliens pop out of vents and pop back in again, get stuck on the ceiling, fall off walls and run in circles." Well, it turns out the game's laughably stupid xenomorphs may have been caused by a typo—more specifically, a single letter mucking up the game's code. As ModDB user jamesdickinson963 explained in a recent post , a line of code in one of the game's .INI files has a small b

The worst marketing misfires and PR moves in PC gaming (and a pair of console flubs, too)

2018-06-08 01:55 UTC · PC Gamer

Image source: The Elder Scrolls Wiki What happens when PR goes awry? Not slightly sideways, as we saw recently with the leak of Rage 2 (which is probably the best thing that could have happened to it anyway) but completely, irretrievably wrong, in a way that inspires conversation and funny stories for years to come? Game publishers do their level best to keep the hype machine running along smoothly and inoffensively—that may be the most important part of all—but sometimes, out of malice or greed or plain old good intentions, the bus goes off the cliff and there’s nothing t

Have You Played Aliens: Colonial Marines?

2016-12-06 15:30 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Brendan Caldwell)

Have You Played? is an endless stream of game retrospectives. One a day, every day of the year, perhaps for all time. You probably haven t and you probably shouldn t. A year before the world finally got the Alien game it deserved with Alien: Isolation, the burning wheely bin known as Aliens: Colonial Marines was dragged into public view and stank out the industry with countless bugs, terrible writing, awful levels and magically teleporting NPCs. There were so many problems, they were coming out of the god damn walls. …

We talk to lawyers about the No Man's Sky false advertising investigation

To better understand the potential consequences of the UK's Advertising Standards Authority's investigation into No Man's Sky, we reached out to a number of legal experts proficient in the realm of video game law for their take on the situation. Stephen McArthur, a "Video Game Lawyer" of McArthur Law Firm , Ryan Morrison of Morrison Lee , Jas Purewal of Purewal and Partners LLP , and Tom Buscaglia, The Game Attorney , agreed to lend us their knowledge and explain what this investigation could mean for Hello Games, Valve, and the industry as a whole.

I mentioned Gearbox’s woebegotten Aliens: Colonial Marines in snarky passing earlier, and so was surprised to see the disappointing Xeno-shooter crop up in the news for Actual Reals. Turns out there’s a mod intended the make the lousy not quite so lousy. My main question at this point is why? …

Modder improves Aliens: Colonial Marines

2016-04-04 09:45 UTC · PC Gamer

Intrepid modder TemplarGFX has overhauled Aliens: Colonial Marines, taking it from middling shooter and legendary disappointment to competent FPS that does some justice to its source material (I fear the disappointment might be permanent). TemplarGFX's ACM Overhaul, on ModDB, focuses on rejigging the xenomorph AI to make them a credible threat. Headshots are essential, acid blood is a constant worry, and aliens have had their decision timing increased by at least 500%. They move and accelerate faster, and every animation has been re-timed to make them look more organic. Hum

Which Digital Game Store Is Best For Refunds: Steam vs. UPlay vs. Origin vs. GOG

2015-07-28 18:00 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Angus Morrison)

Rumour has it that the decrepit Arkham Knight port beat a retreat on account of Steam refunds. After all, what better way to get a dastardly developer to blush and shuffle its hooves than to reverse its cash flow? Until June, when no-questions-asked refunds came into force, such a feat was impossible. Perhaps, after years of pro-consumer jabs at Microsoft and other corporates, Valve sought to make a material gesture that player interests are truly the heart of the Steam empire. Or perhaps they dislike being sued. Hint: they are currently being sued. By now, you ve likely encountered a shop and

Randy Pitchford defends Aliens: Colonial Marines and Duke Nukem Forever

2015-07-24 18:49 UTC · PC Gamer

The likelihood is that, if you played Aliens: Colonial Marines or Duke Nukem Forever, you didn't much care for them. Maybe they were buggy, or maybe they didn't look as good as you expected, or maybe they were just offensive. For a variety of reasons, lots of gamers just did not like them. But Gearbox boss Randy Pitchford insists that he did—and he knows how much that bugs people. "I liked . And it frustrates the people who didn't to hear me say that," Pitchford said in a long and wide-ranging interview with Eurogamer. "It's almost like they want to hear me say, yeah, it was rubbish

Gearbox boss says Colonial Marines lawsuit was like "Mafia-style extortion"

2015-07-10 19:37 UTC · PC Gamer

My favorite thing about the legal action filed over Aliens: Colonial Marines is the way Sega tried to portray Gearbox boss Randy Pitchford as a loose cannon. He was initially seen as a "respected development celebrity" who would help garner coverage but, like a cane toad in Australia, once he got going, there was apparently no stopping him. Now that the matter is effectively over, Pitchford is speaking his mind again. "That whole thing was a huge waste of time," he said in an interview with GamesIndustry. "The market proved it was doing its job perfectly. The market is dispassionate—rewa
