i think the only worm game to have this was the first one, where each map had its own properties, like the old mars level, it had low gravity, and the alien map had low gravity and a slippery surface, any chance this is coming in worms reloaded, and if not why? i always missed that and it seemed like it added a nice challenge for each battle

Worms Open Warfare 2 and Worms A Space Oddity featured that stuff. Examples: Cold War theme (playing on icebergs) in OW2 was very slippery and there were dangers like rising water and earthquakes from time to time, while in Space War there was low gravity. On Cavernia you were playing in a city build within a cave thus no wind was blowing.

Worms Battle Islands which (hopefully) releases soon on Nintendo Wii and PSP will also feature it. I would like to have it in Reloaded, too, but oh well.

I'm all for this! I loved those effects.
