The lights are on
Tank! Tank!! Tank!!! is free on the Wii U eShop, but in a slimmed-down version with some of it's modes turned into DLC for purchase.
The game generally reviewed flatly, impressing almost no one. It was considered fun, but overall pretty dull and it had a singular noted broken gameplay mechanic--not being able to shoot in one direction while driving in another (what kind of tank is that?!).
That said, it's still a free eShop game right now, so what the hell?
It's 1.5 GB, so it's apparently not skimmed down to a ridiculous level, apparently.
Again, not a great game, but a free game right now.
