Mercury Meltdown is a puzzle-platformer game for the PlayStation Portable where players control a liquid Mercury blob, navigating through various obstacles to complete levels. The game features four distinct states—Normal, Solid, Fast, and Slow—enhancing gameplay complexity. With over 160 levels and support for downloadable content, it includes a wireless multiplayer mode featuring five competitive sub-games.
Once again taking control of the liquid Mercury 'blob', players must avoid various obstacles and hazards to reach the end goal. The Mercury blob itself has now been given an overhaul and has 4 varying 'states' - Normal, Solid, Fast and Slow. These states allow for larger more complex levels, which in turn mean a greater challenge and more enjoyment to be had for the player. The number of levels has more than doubled - now 160+, and with the newly added feature of Downloadable Content more levels will be made available at a later date. Wireless 2 Player modes have also been an important addition, with 5 sub games each providing a challenge against the computer or a friend.
