Serving as a prequel to Wolfenstein: The New Order, The Old Blood finds gamers guiding Captain B.J. Blazkowicz on two missions deep inside Nazi Germany. There are a handful of new weapons to wield and a variety of new enemies to battle as layers can wield a handful of new weapons as they break into Castle Wolfenstein, battle an evil prison warden, and try to discover the location of General Deathshead's secret compound. The action then leads to the city of Wulfburg, where an ancient and destructive power is being excavated by a Nazi archaeologist.

As in The New Order, The Old Blood doesn't let players recover health simply by avoiding combat for a few moments. Health regenerates in small segments, and gamers must use a cover and lean mechanic to avoid taking too much damage, while locating health or armor to fully recover. There are also numbers of perk trees that reward gamers with upgrades and new abilities depending on the way they engage in combat.
