Warner Brothers may be planning to use a sneaky Steam tactic to conceal negative reviews of Batman: Arkham Knight.

A bundle has appeared on Steam that features only a copy of Arkham Knight - hardly a bundle.

Bundles on Steam do not include reviews, as some bundles contain many items, making it near-impossible to consolidate reviews.

Thus, advertising a bundle with only the game could be a way to obfuscate poor user review scores.

Arkham Knight's Steam reviews currently sit on 46%, thanks to a disastrous PC launch marred by performance issues and bugs.

The bundle is not yet visible on the Steam front page, so this development should be taken with a grain of salt.
