Bundle Stars’ latest bundle is a compilation of basically every major Batman: Arkham game, plus DLC.
It’s a bit pricier than most bundles, priced at €9.79 (£7.72 or $12.12, according to currency conversion) but I don’t think you’d have much difficulty arguing it’s worth the price. That $9.79 gets you Batman: Arkham Asylum – Game of the Year Edition, Batman: Arkham City – Game of the Year Edition, last year’s Batman: Arkham Origins, the Batman: Arkham Origins Season Pass, the Black Mask Challenge Pack, and the Online Supply Drop 1 & 2 DLC. Which is pretty much every Batman: Arkham game on PC that I’m aware of, barring the Arkham Origins spin-off Blackgate.
Arkham Asylum and Arkham City are a pair of utterly triumphant titles, and Arkham Origins… well, it’s not bad. It’s just not up to the level of its predecessors, and it tends to follow them Arkham City a little too closely rather than doing anything new or interesting.
While we’re on the topic of Bundle Stars selling stuff for cheap – if you fancy a bloody and brutal brawler instead, then Mortal Kombat: Komplete Edition is €4.00 on the Bundle Store for the next two days.
