Following the announcement of Batman: Return to Arkham, images comparing the original versions of Arkham Asylum and Arkham City with their remastered versions have appeared.

Reddit user blackfire561 has taken a selection of scenes from Return to Arkham trailer and found the corresponding shots in the original versions of Asylum and City. This has provided a good look at what rebuilding the games on Unreal Engine 4 has achieved. A few of the images can be found above, but the full set is here.

Both Arkham Asylum and Arkham City were developed using Unreal Engine 3, but Chinese company Virtuous opted to use the latest version of Epic's game engine for its remasters.

In addition to the base games, players receive all Game of the Year extras and downloadable content in Return to Arkham. Overall, Warner Bros. said players can expect "improved graphics" and "upgraded models, environments, lighting, effects, and shaders."

Return to Arkham launches on July 26 and will cost $50/€50/£40.

The first two Batman Arkham games gained near-unanimous praise in reviews. GameSpot's Arkham Asylum review said "everything about this game--the impressive visuals, stirring soundtrack, superb voice acting, fiendish puzzles, hard-hitting combat--feels like it has been lovingly crafted by a development team that's both knowledgeable and passionate about the source material."

Arkham City was also rated highly: "From the speedy exhilaration of soaring high above the streets to the atmospheric thrill of discovering long-forgotten secrets in the tunnels below Gotham, this is an unforgettable adventure that will keep you coming back to the cape and cowl long after you've seen the credits roll."

Batman: Arkham Knight, the latest in the series, was released in June 2015 and has reportedly sold 5 million copies. It is apparently the last Batman game developer Rocksteady plans to make for the foreseeable future.
