Following yesterday's announcement that Nibris is developing DS title Raid Over the River, the Polish studio has shed a bit more light on what we can expect.
Apparently there are six campaigns to play through, and they all take place in different dimensions - including ancient Greece, Europe during World War II, Soviet Russia during the Cold War, present day USA, and Germany circa 2018. Oh, and Japan at some point in the "unspecified future."
You get a different vehicle for each location, and loads of weapons, such as sonic blasters and plasma cannons. You can also take on the enemy with intelligent missiles, particle blasters and gravity bombs - or even order a laser attack via satellite.
