Caladrius an upcoming shooter from Raiden developer Moss is trying to cater to diehard fans of the genre and newcomers. Caladrius is story heavy with visual novel-like cutscenes where you see Alex, Kei, and Maria talk. If you just want to play through the story you can select "No Damage" mode which makes your ship invincible.
Enemy bullets, boss laser beams, and crashing into stuff won’t destroy your ship in this mode. However, a damage counter underneath your score lets you know how many times you would have died. Caladrius has online leaderboards, but won’t have one for No Damage mode. And if you’re a shooter fan you can select "very hard" mode, one of the six difficulty settings in the game.
