This game would deserve a neutral rating. The last update was in 2016. I’m writing this review in 2026.
It’s a functional game that built its existence on combining retro gameplay from the CRT monitor era at 800×600 resolution with the modern era, where, at the expense of gameplay, you create an environment filled with every possible and impossible effect so that even the top graphics hardware of the time can barely handle it.

The result is a functional (everything works, it never crashed once) but uninteresting game, where you don’t have a strategic view; even the maximum zoom-out doesn’t show your entire base, and the zoom-in is so close that if it weren’t a top-down view, you’d be looking straight into the units’ anal cavities.

Three uninteresting to outright repulsive factions, a cluttered, overwhelming environment — a jungle. I gave this game many chances, and always ended up at the same point.

Who plays on a 14" monitor today? Not me. Today, 27" and larger monitors are common, with QHD resolution and higher. If you have a standard desk, you’re looking at the monitor from a distance of 60 to 80 cm.

Instead of implementing a strategic zoom so you could view the entire map — something that has been standard for many years — you’re staring at something like the face of a cat that came to rub against your nose. You try playing in windowed mode, but you’re still constantly zooming, and it just doesn’t work.

I tried a laptop. A 15.6" screen. Here’s the other extreme. You have an Intel Core 5 Ultra processor with integrated Arc graphics versus a 10-year-old game. You have to turn off almost all effects to get above 30 FPS. You have a base, nothing is happening, just jungle — yet the GPU runs at 2200 MHz and nearly 100%. And it all looks blurry.

I tried the campaign several times. Why force yourself to play a game that its own creators abandoned after a year, that almost nobody plays in 2026, with ugly environments and factions, when there are both old and new RTS games — many of them free — that are alive, clear, undemanding, and fun?

Why spend time on the dead Grey Goo, which preserves gameplay built for the 800×600 past, when there are things like cncnet.org with C&C and Red Alert (or the original bundle of all C&C, Command & Conquer The Ultimate Collection)? When there’s Supreme Commander? When there’s Zero-K, Beyond All Reason, and many other truly high-quality RTS games that weren’t made just as technological demos to show how many graphical effects can be used at the expense of gameplay?

Grey Goo could have been a good game. But that strategic zoom that Supreme Commander has had for 20 years — Grey Goo instead used 30-year-old limitations and layered ultra-demanding, unnecessary graphical effects on top, giving the impression that 90% of the time was spent only on making the environment more complex and more demanding. The result is a boring, blurry-looking, unremarkable, dead RTS game with a dull story, created in the same era as Ashes of the Singularity: Escalation — a game whose developers still support it, and which, if nothing else, was used as a benchmark in its time.

So I don’t end on a negative note:
The most satisfying feeling Grey Goo can give you — and it truly is an almost uplifting feeling — is confirming the uninstall and watching even the last remnants of this “gem” disappear from your system.
That feeling of cleansing is priceless.
