On the resident evil Arena first you will choose a character to be, then you will face random character from resident evil series, whether its a monster, human or anything else. The fighting is tour based meaning that you say what you do and there is told what is happening then enemy does the same. Rememeber, you oonly fight, say what you are doing, you cant say what is happening exacly on the battlefield for example what is happening with the oponnent.
