There are plenty of imperfections on Requiem’s grander canvas. It is unevenly paced, with a number of ponderous lulls. It has plenty of nagging inconsistencies (how are we expected to believe that our heroes consistently fall into areas where there are no rats?) and repeated puzzles (we lose count of the number of times we fire Amicia’s sling through a side window to remove an obstacle from behind a door). But at its core it has a secret weapon that disguises many of those blemishes and allows you to appreciate the bigger picture. It’s the same one, in fact, that made the first game such a pleasant surprise three years ago – the sibling relationship between the De Runes once again supplies A Plague Tale’s emotional heartbeat.
