Help Lara attack Tyler's gang

 is a quest in Fallout 2.

Background
After finding a weakness in Tyler's gang, Lara will refuse to pay you unless you join them in the attack.

Walkthrough
The gang at the church consist of 5 NPC's, one armed with a Sledgehammer and four armed with 10mm pistols. Stick around long enough to watch Lara's gang cut down Marc, the doorman. You can then talk to Lara to receive your payment.

If you step inside the church during combat or after Marc is dead, you will have to fight the other 4 NPC's, as they will go hostile. Be careful not to hit any members of Lara's gang!

An alternative to the solution suggested in the quest title does exist. When Lara first gives you the quest, tell her you need to prepare, then quickly shoot over to Tyler and inform him about Lara's cunning plan. Tyler will request for you to follow Lara to the church as normal, but turn on her when the battle begins. Doing so will net you the same 1000 experience points and some negative karma.

To spare the lives of the guards inside the church from Lara's gang, close and lock the door to the church before accepting the mission. So long as the player's character does not attack and damage Marc, the guards within the church will remain neutral to the player and to Lara's crew even after Marc has died. Lara will reward you and the quests is completed. Lara will reward you after Tyler's partner Marc is vanquished and combat is ended. You may then unlock the door and let Lara's crew inside, where no harm will come to the four guards although they are still flagged as hostile. To resume hostilities, simply fire upon a guard.

Fallout 2 Restoration Project changes
After the church guards are dead, you need talk to Lara to continue the quest and go with the gang to The Den's residential area where Tyler's friend's party takes place. There you help Lara dispose of a drunk Tyler, his friend and the remnants of his gang. You do not need to worry about Lara or her gang members health, as they regain all their hitpoints doing the transition. After this Lara and her gang returns to the church where you can pick up your reward.
