Incoming was one of the very first games to hit the Japanese Dreamcast, and was a near perfect port of the original PC game. Many dismissed the game as a 3D accelerator Tech Demo of sorts, but there was actually a game behind those pretty graphics and special effects. Graphically, the Dreamcast version is excellent. The martian environments, alien spacecraft and structures are nicely modelled and textured. The explosion effects and dynamic colored lighting are all especially impressive. The sound effects are crisp, and the music is of the pseudo-movie soundtrack variety.

The gameplay is simplistic, but can be engrossing on occasion. You control a number of war machines designed to shoot down or blow up alien spacecraft and tanks; everything from ground mounted anti-aircraft guns, to attack choppers, to tanks are accounted for. The control scheme for each craft is different, and sometimes that can be confusing. After a few minutes with each, however, the issue seems to disappear. The crafts usually are equipped with a cannon with unlimited ammo, as well as some more powerful Missiles or special weapons.

The missions usually require you to annihilate waves of alien tanks and craft, but occasionally some other goals are thrown into the mix. Picking up and delivering supply crates, locating and retrieving a damaged alien spacecraft, and even taking down tremendous motherships are among a few. In general, Incoming features much more mindless blasting than anything else.

The missions obviously become more difficult as you work your way through the game, but the level of difficulty never becomes overwhelming. There are a decent number of missions, though it doesn't take very long to work through them all. As a result, the game is a bit on the short and easy side.
