Targetenium Trophy in Mercury Hg

This will be one of the first trophies that you get. Each level has four targets (atoms) to complete. The targets are completion of the level, amount of mercury remaining, time, and bonuses collected. The first level (Hydrogen [H]) is by far the easiest to do this in as all four targets are easy to reach. The four targets for Hydrogen are listed below.

Mercury – 100%
Time – 30:00 seconds
Bonuses – 3
Level Complete

If by some chance you only reach three of those targets, you can go and reply the level to get the fourth one and the trophy will still unlock.
