The plot of N2O is simple - diabolical giant mutants, biomechanical insects are trying to take over the Earth and you have to fight them in a very bizarre "pipeline", shaped like a torus and called The Torus. It was created by these Superwarriors (i.e. insects) to attack the Earth, and you and your faithful Tonnel Runner must eliminate all this disgrace in the bud. You know how to steer, shoot, jump, dodge attacking hordes of insects and deal with obstacles. Deliver the required number of hits, score a lot of points and move on to the next of 30 game levels. If you failed to completely destroy the next wave of insects, then they will return at the same level back, but in a completely different color. And it will be much more difficult to remove them, more attacks will be required, but you can earn more points. So you don't have to kill someone on purpose.

Choose a suitable transport for yourself - each has its own advantages and disadvantages, which are determined by the difficulty of the levels and the manner of your attacks. The concept of the game, the control system, the visual image, the scenario, the nature of the game action and the whole atmosphere of the N20 do not contain anything extraordinary, but there are many small innovations relative to its predecessor - Nanotek Warrion. There are noticeably more levels, it is possible to use analog and Dual Shock controllers, a two-player mode (cooperative) with split screens and such a necessary memory card. The game, of course, turned out not bad, but the continuous monotonous waves of insects soon get bored, especially in a monotonous pipe.
