Sales of Arkham Origins were similar to the original Arkham Asylum, but the prize for the best-selling opening weekend of a Batman game is still held by Lego Batman, Chart-Track adds.
Grand Theft Auto V was second in the UK charts, followed by FIFA 14 in third and Skylanders: Swap Force in fourth.
Pokemon X and Y were fifth and sixth, respectively.
New in the chart this week was the latest Moshi Monsters game in ninth, and Rocksmith: 2014 Edition in 15th.
