Archer Maclean's Mercury is a third-person strategy game with puzzle elements from the developers of Awesome Studios. The game is published by Ignition Entertainment Ltd. USA. In some circles Archer Maclean's Mercury is also called Hg Hydrium. Perhaps Archer Maclean's Mercury is being developed for PC, but this version has not yet been announced. Overall, the project turned out to be rather weak. Most reviewers gave the game very low ratings.
