This is the game Warring Worms with several improvements.
These include:Tank Mode: in this mode, you do not leave a trail behind you when you move.
Solid Arena Mode: the obstacles in the arena cannot be destroyed by your cannon, only worm trails or heads.
Unbreakable Mode: your cannon only hurts the opponent's head. Nothing else is affected by it.
First To: this allows you to set the ending score so game length will be manageable.
Sudden Death Mode: in this mode, if any player gets two points ahead of the other, they win.
Select Game/Random Game: selecting Random game changes most game options randomly before each round.
