Help Lara attack Tyler's gang

Upon getting Metzger's permission to fight Tyler's gang, and talking to Lara, she'll say that you won't get paid unless you join them in the attack. You don't have to fight just be there.

The guards at the church consist of 5 NPC's, one armed with a Sledgehammer and four armed with 10mm pistols. You only need to kill Marc, the one in front, as you will be then able to exit combat mode and talk to Lara to receive your payment and a $100 extra.

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.
