Following Zimmand Company's Gogg, the Zeonic Company produced their own amphibious mobile suit for the Principality of Zeon, the MSM-04 Acguy. Acguys used many of the same parts and components as the Zaku II, including twin ultracompact fusion reactors. However, even with the twin reactors, the Acguy left only a trace heat signature, making it effective for stealth operations. Several Acguys were used on a covert mission to sneaked into the Federation's Jaburo General Headquarters and destroyed the Federation's mobile suit production facilities, which were being used to produce their RGM-79 GM mobile suits.
This suit is very much the epitomy of the entry-level suit for most Zeon H2H users. Being able to weild the fairly MS Mega Particle Beam Gun is great benefit to this fairly cheap suit, and should suit most players choosing to play a H2H/Beam based build very well until they are able to get their hands on either a Z'Gok E or a Z'Gok S. Like most H2H suits, you will either want to go for either a mix of attack power/accuracy, or accuracy/defense power on a custom suit.
