You control the cute Cool Coyote who's quest is to go through eight worlds in pursuit of the evil wizard Suten. In each level you collect pieces of a key which will give you access to the next part. Those pieces can be found via monsters which will drop pieces of the key when killed. Attacking a monster works by shooting ice pellets at it. Note that this causes no damage though, but only will freeze it for a short time after having received enough hits. Any monster can then be killed by touching it as long as its frozen.
There are also, there are hidden warp gates that will transport him to other lands and possibly hidden bonus zones. The game is a cute but difficult jump 'n run platform with pretty sensitive controls, so that you'll need quite a bit of manual skill to get your Coyote where you want him to be. Nevertheless, it's a fine arcade platform, with huge of playability!
The Atari STE version of Fire and Ice is an enhanced ST version (but it could still be a standard ST game with a very well chosen palette) that features a very nice gradients for the sea and control panel (but not for the sky). It is using 16 shades of blue all on its own, surely there is a bit too much color in this game to be a standard ST game (there are around 110 colors on screen!). Note that, the impressive shimmering water effect at the bottom of the screen found in Amiga version of the game, is missing here. Also, both foreground and background scroll smooth enough on the STE models. Whilst the STE models have Blitter chip (acting as a coprocessor for loading large memory data to the CPU, much like Amiga models), much foreground detail is missing here in contrast to the Amiga OCS/ECS and AGA versions. Graphically though, the game looks pretty good on the ST (around 40 colors on-screen)!
The sound is identical to the standard ST version, having in-game SFX but no background soundtracks (in contrast to the Amiga OCS and AGA version).
