"Haydee" is a hardcore old-style metroidvania mixed with modern-day third person shooter and platformer mechanics. You will controll Haydee - half-human, half-robot character in search of her way out of strange artificial complex full of traps, pain and depression. No casual stuff awaits you. There is no "X to win". Your gun, your instincts and your logic are your only friends. Don't drop your guard, conserve ammo and collect items on this long journey. Be vigilant, be sharp, be ready.
