Thunder Heroes (2001 Arcade) - Razorface Live
Thunder Heroes Arcade PCB was released in 2001 by a company called Primatec (Primetek) Investments, which is a direct remake of Gaia Crusaders. To differentiate the characters, most are palette swaps with their clothing changed and names have stayed the same. Most of the levels and enemies are also scrambled and palette swapped. Rob is completely absent, with Getuki replacing him.
Thunder Heroes is notably shorter than Gaia Crusaders and a lot easier too. There are only five levels, holding one piece of a magic pentagram each as opposed to the seven shards of the demon's tear. Enemies have less health in general and many weapons that were not in the original are present. New weapons include lead pipes and energy swords, which function just like the sword from the original. The other new weapons are knives and grenades, which are tossed immediately after use. -- Watch live at https://www.twitch.tv/razorfacelive
