Blasphemous has another free expansion out now with Blasphemous: Strife & Ruin, pulling in Miriam from Bloodstained: Ritual of the Night along with more free content.
Tasked with helping Miriam return to her world, you go through a series of platforming challenges and collect shards to repair a portal for Miriam to go home. Filled full of traps it's a challenge mode to improve your precision platform abilities and you get a special reward if you manage to finish it.
Another major addition is the Boss Rush Mode, which you need to complete the main story to access. This mode features courses containing a selection of bosses that you take on using any save file and each has a score attached to it with medals awarded.
You might also spot an arcade cabinet hidden in a secret location, that allows you to play through a special "Demake area" that pays homage to classic 8-bit platformers. This special mode has the mechanics tweaked too which they say was done to match the classic styling. On top of that, there's also some new built-in retro rendering modes to emulate old CRT screens for those that want to go hard on nostalgia.
