Sonic Ironstorm is a vertical scrolling shooter, originally based on a 3-minute competition.
There are five difficulties within the game, ranging from Easy to Shooting God; the highest difficulty is locked and is only available in stage select.
You have a choice of two fighters.
- Valiant Fighter, which has a more focused fire towards the front and a torpedo. (You can tap 'Z' for a tighter formation of missiles, and press 'X' while torpedo is flying to manually detonate it.)
- Spear Hawk, which has a wide firing pattern, and a targetted napalm. (Hold 'X' to increase firing distance, and release to fire. Holding 'X' also increases movement speed slightly.)
