Hello!

I'm posting in this forum as I can't see a dedicated forum for Worms Special Edition for Mac (as far as I'm aware, it's the same game as Worms Reloaded?).

In single and multiplayer games I occasionally get crates with either Steal or Invisibility, neither of which appear in my weapons inventory, is there something I'm missing, or is this simply some kind of glitch?

That doesn't sound right, I will get someone to look into it. Steal and Invisibility should not be appearing at all as there is no online play in this game.
