While the official site for Gungnir has only recently gone up, an online retailer has slipped some details on the game’s battle system, as well as other pieces of information on the game. When the game was first revealed in Famitsu, very few details were given on the battle system, except to mention the Tactics Gauge and the Act Sequence. According to the retail listing, the Tactics Gauge is used to change the order of unit movement and execute support moves and team attacks. The gauge must be filled to do so, though how is not specified.
While no information was given about the Act Sequence, the listing does mention that Gungnir will have media install support, multiple difficulties, and a guide feature to help first-time players of the game. The latest game in the Department Heaven series will hit the PSP on May 19 in Japan.
