Ira

High up in the heavens, the ancient crystal known as Ira maintains the peace of an entire world... until a mysterious figure shatters the crystal, allowing Chaos to return. As malevolent creatures suddenly appear across the land, a young girl is chosen by an ancient god to collect the fragments of Ira and restore order, assisted by the apostles who once served Ira’s creator. A character-based shooter with roguelike elements, IRA celebrates the artistry of what shooter fans call “bullet hell”: enemy projectiles that weave intricate, geometric patterns across the screen and force you to seek out the precarious safe spaces between them. Set in an Eastern-influenced fantasy world marked by ethereal beauty as well as grave danger, it’s a procedurally generated action game that requires skill, inspires strategy and rewards patience. FEATURES: Shoot arrows from 166 different bows Choose three special “perks” (power-ups) each time you level up 150 unique relics (passive buff items) 43 different synergies from bow + relic combinations 5 different Apostles that can be conjured for special ultimate skills and passive perks Procedurally generated maps across more than six different stages Boss battles with exceptionally devious projectile patterns
