Fun for a while, at least...
The game's premise is simple - a runaway truck carrying a nuclear weapon is careening towards heavily populated areas around the world at blazing speeds.... ok, so, maybe not "blazing", per se. More lke, cozy Sunday drive speed.
What to do? How are we to prevent the destruction of property and enitre civilizations? Destroy a select few buildings to clear a path for the runaway death machine, that's what.
So the plot doesn't deserve an award on its own, but it does make for some tense and involving gameplay. Bulldozers, dump trucks, rocket-propelled mechs (among many other vehicles) help attain this goal of destruction before the nuke makes even the slightest contact with one of the buildings. You jump from vehicle to vehicle, using the terrain and vehicle abilities to your advantage.
This may sound like fun at first, but it makes individual level gameplay linear and somewhat frustrating to get sorted out. My own experience with the game is fairly limited, because the game gets progressively difficult to the point where it's just not fun anymore.
While the concept looks great on paper, Blast Corps just doesn't manage to pull off a genuinely fun product.
