The themes of the original Half-Life game are expanded with oriental and futuristic ones. Since the theme has not been defined, the maps are extremely diverse. In addition to the entries in the map, the node contains a healing pool, which is recommended to be used after every return. The maps are not directly linked to one another, but they connect via a teleportation node. ReIssues or Project Quantum Leap 3 is a compilation of maps of various authors in which you have to complete the tasks of your employer, the mysterious G-Man.
