At GamesDay 2010 Forge World had on display the Grot Mega Tank. I really do like this model alongside the Grot Tanks. The model is very ship like with battleship style turrets and a prow shaped bow. It is a very ramshackle vehicle and looks like (as it should) if the grots have just thrown it together from parts lying around the battlefield and stuff stolen from a Mek workshop.
The turrets are interchangeable with those of the plastic Ork vehicles and the Grot Tanks allowing you an opportunity to convert the Mega Tank into a different looking model. Useful if you were to get two.
Designed by Stuart Williamson, the Grot Mega Tank represents the pinnacle of Gretchin-built Heavy Tank technology; an overpowering war machine that drives all before it in a storm of scrap and destruction. This full resin kit is festooned with unique details as you can in the images, and Stuart has designed each turret to be fully cross-compatible with Daren Parrwood’s Grot Tanks.
Hammered together out of junk, spare Mekboy know-wotz and unbridled Grot enthusiasm, the Grot Mega Tank adds even more firepower to the battlefield madness that has come to be known as a Grotzkrieg, terrifying Imperial Tacticians, Eldar Farseers and Chaos Warlords alike.
It was also available to buy on the day and I did manage to get one.
