As with other Dept. Heaven series titles, the turn-based tactical role-playing game unfolds across grid-based battlefields. Lore draws from Norse mythology, by way of protagonist Giulio Raguel's spear Gungnir. The weapon's five Norse-themed Inferno summons, including Einherjar and Midgardsormr, exhibit customized effects to aid the party in battle.
The 52-track soundtrack album by Blaze Union composer Shigeki Hayashi was pressed on compact disc in 2011, published by Team Entertainment. The digital edition is streaming on Apple Music, Spotify, YouTube Music, and Amazon Music Unlimited, published by Atlus Game Music.

Building upon the traditional action queue of turn‐based SRPGs, actions in Gungnir all have a numerical wait interval associated with them. Faster actions bear smaller numbers, allowing them to precede slower preexisting attacks.Gungnir (Soundtrack) - Apple Music / YouTube Music
