Over Dose!! is a push-your-luck card game from Japan. Players are scientists trying to awaken a beast in a cave. But the scientist who injects too much, gets eaten. The players are trying to edge on their competitors to get eaten, so they leave with all the credit. In the depths of an abandoned mine, a Hexenbeast, described in an old book, was sleeping in a state of suspended animation. One day, a group of mad scientists discovered it, but they were not satisfied with just examining the beast in its dormant state, they wanted to wake it up and observe its activities. However, according to the literature, a large amount of activator is needed to wake up a Hexenbeast, and the waking Hexenbeast will immediately eat the person in front of it. The scientists are not on the best of terms. The fewer people who take their findings home with them, the better. This is the perfect opportunity to kick off a ridiculous game of chance! ã¨ã‚ã‚‹å»ƒå‘ã®å¥¥ã€å¤ã„æ–‡çŒ®ã«è¨˜ã•ã‚ŒãŸé­”ç£ãŒä»®çœ çŠ¶æ…‹ã§çœ ã£ã¦ã„ãŸã€‚ã‚ã‚‹æ™‚ç‹‚ã£ãŸç§‘å­¦è€…é›†å›£ãŒãã®é­”ç£ã‚’ç™ºè¦‹ã—ãŸã®ã ãŒã€ä»®æ­»çŠ¶æ…‹ã®é­”ç£ã‚’èª¿ã¹ãŸã ã‘ã§ã¯é£½ãè¶³ã‚‰ãšã€ç›®è¦šã‚ã•ã›ã¦ãã®æ´»å‹•ã‚’è¦³å¯Ÿã—ãŸã„ã¨è€ƒãˆãŸã€‚ 　しかし、文献によれば、魔獣を目覚めさせるには大量の活性剤が必要で、しかも目覚めた魔獣は即座に目の前の人間を食べてしまうという。 科学者たちは決して仲良しではない。得られた成果を持ち帰る人間は少ないほうが良いのだ。これを機にライバルを蹴落とそうと、とんでもないゲームが始まった！
