Namco Super Wars is a crossover game, featuring characters from several classic Namco titles.
The game is played on a square grid, on which both the player's and computer's units are placed. Each side takes turns moving and making actions with their units. Every character has a variety of attacks and special moves that can be selected when performing an action. Some of these consume Spirit Points, which slowly regenerate each turn. The game is divided into stages. Between each stage, the player is able to visit a shop and prepare his units before starting the next stage. Unlike most RPGs, characters do not gain levels for directly defeating opponents. Instead, completion of a map will reward the players with a number of level ups, which they can then distribute among their units as they wish.
As a crossover game, Namco Super Wars includes characters from a number of previous Namco games. The games represented are the following.
Valkyrie no Bōken: Toki no Kagi Densetsu / Valkyrie no Densetsu
Dragon Buster / Dragon Valor
The Tower of Druaga
Genpei Tōma Den
