Mafia 75. The Mystery of the Ancient Ruins.

Now he'll just sit and wait until we finish each other off.

In that case, you can hang him like Horatius, and Mana can be executed normally. And finishing off/hanging Damien shouldn't be a problem. According to my table, Neyra and Rita are the most likely candidates to be defeated by Mana, but I don't understand who is who. Regarding Ment and Koshi, I can't say; Ment is clearly playing more usefully than Koshi, but I remember that they play completely different roles. However, this isn't a problem if he uses his DD Horatius. But if he uses it, then you need to buy Markelius, otherwise you'll have to look for Mana right away.
