Gameplay over the Internet is smooth, with hardly any lag and the quality of players online is really good. I probably would do myself a favour by practising more in the single player modes.
It is best to choose a intermediate weapons payload in a multiplayer game as some of the weapons available in the full mode can be potential game-breakers, especially the Donkey. It's fun stamping on opposing worms but once it becomes the weapon of choice between two combatants, it's definately a kill-joy.
Anyone looking for a Friend Code match? Do add my friend code to your Friends list in Worms Open Warfare 2. Looking forward to some warm worm war action online :P.
