Scenario I: Santuario Por Favor Padre

Teams: One/Two posses
Location: The Las Hermanas House of Sanctuary
Suggested avatars: Defending Posse - One group from Dutch's gang, Walton's gang, cattle rustlers or misc. criminals; Attacking Posse - Ideally Federales, but also misc. mexicans or rebeldes.

Scenario: A gang of gold thieves are being chased across Mexico by the Mexican Army, who have been hot on their heels since Escalera. A posse determined to get the astronomical bounties placed on their heads also join in the chase and, with their mounts flagging, the bank robbers are forced seek sanctuary in the religious house at Las Hermanas.

Rules for one posse: Get everyone inside the grounds of the house, and then everyone open fire on those inside. Start the timer from the first kill (all members should have a bounty), and then keep killing until you've all died and are spawned outside the grounds. Those outside are allowed to draw fire from the military in the small railway stand to the south east, until they outnumber those inside.

Rules for two posses: One posse starts in the grounds and one outside, with those on the outside aiming to kill everyone inside in as quick a time as possible. Once a member of the gang has been killed, they must stay outside, and are only allowed to interfere with the attackers with a melee knife.
For added danger, the gang inside must get bounties on their heads so they are facing off against two threats, and in this instance you may want to allow the dead robbers to solely attack the Mexican military outside.
