Cancelled Valve Project Stars of Blood Reappears with Leaked Screenshots

Some have emerged from the ValveArchive site Images attributed to Stars of Bloodwhich should be a Valve game cancelled from the company, about which very little is known but which these illustrations could help to understand better.

We don’t know exactly what stage the development of the game was at when it was cancelled, but at the moment there are no materials actually related to the gameplay or the phases played, so the leaked images are concept art and illustrations which can however highlight settings and themes covered.

It’s also difficult to guess typealthough Valve’s curriculum leads us to think about the possibility that it was a first-person shooter or some type of action adventure, but these are only suppositions.

A fascinating setting

What clearly emerges from the illustrations is thescience fiction settingwhich is also very fascinating as it presents some original visions of the genre, mixed with more canonical elements.

In one image we see a colossal creature with a decidedly alien shape, in others there are spaceships and mega-structures with proportions impressive, which might indicate something about the overall scale of the game.

With 336 employees and revenues over $17 billion in the last year, Valve is the most efficient company ever

In any case, it is likely that Stars of Blood never reached the actual production phase, perhaps stopping at the prototype, however from what we can see it seems to be an extremely fascinating project.

In the meantime, Valve presented Steam Machine and other hardware products, while on the software front there is still no news, despite some sources taking it almost as certain upcoming news on Half-Life 3.
