- Two playable characters: Freyr and Freyja. They're siblings in the game, which is based on Norse mythology and Ragnarok.

- Freyr uses melee weapons like swords, spears, hammers, etc. Freyja uses range weapons like bows and magic. The 300+ wepaons available in the game are separated between the two characters. It's totally like EDF2.

- You are allowed to bring 3 weapons into each mission. When you defeat enemies, you gain mana. You use mana to "create" new weapons using alchemy. I suppose it's easier to just think of mana as currency, and new weapons as stuff you development along weapon trees available for each character.

- There are NPCs in various missions, like villagers running for safety, or other soldiers fighting alongside you. Similar to how it was in EDF2 and EDF3 I suppose.

- The game is normally running at 30fps, but like all Sandlot games, the framerate is "variable" (lol). It can climb up to 60fps, or dip to below 20fps. Apparently the game is programmed to take these framerate drops into account so it won't hinder the actual controls in the game, but... lol anyway. EDF!!!!!!!

- There are 5 difficulty settings for each mission, like in EDF. Very Easy, Easy, Normal, Hard and Inferno.

- For range weapons, Freyja uses homing and lock-on to fire her arrows. From what he says, it sounds like how ZoE and Panzer Dragoon handles it. A bow at lvl1 can apparently lock on to 4-6 targets at once, but the number increases with higher level weapons. When you use magic, it consumes MP, which you regenerate by defeating enemies. Not sure if MP is the same as Mana.
