One target, one city, multiple assassins, 100 million dollars. This is a free roam, open ended roleplay in which each player is an assassin *or possibly even the target/handler, if someone wishes to play that role* all hunting the same man/woman in an attempt to claim the grand prize. While the target definitely won't be a cake walk, the main conflict comes from the tension between each of the assailants, in a race against the clock to earn the reward.
When it comes to boundaries, there are very little. Of course, I won't allow a marry sue with someone running around, being able to take out everything in their way and instantly snapping the targets neck, but you can go wild. Want a ninja like assassin with swords and daggers? go for it. Want a more traditional hitman, black suit, suitcase and a sniper rifle? go for it. Want a more foreground assassin, setting up traps/keeping inside tabs? boom, allowed.
If enough interest is generated, i'll add more.
