Time Stalkers

Time Stalkers, also known as Climax Landers (クライマックス ランダーズ) in Japan, is a Dreamcast role-playing video game featuring appearances of worlds (and playable characters) from several of Climax Entertainment's earlier games in crossover fashion. The player initially takes the role of Sword, a character caught in a world made of many worlds. As he goes along, similar heroes show up for the player to control. The player may do things such as enter dungeons, take special assignments, and upgrade/buy/sell items.
