Dying Light - All 9 Poster Challenges (Old Town) Plus BOZAK Meet & Greet

Hi Guys - anybody out there still doing these challenges? Hope you find my strategies helpful. Word of warning: at least one of Bozak's trials requires the player to have the TAKEDOWN skill, and another might potentially rely on your having unlocked TIC TAC. VAULT STUN is handy, but not essential. https://store.playstation.com/#!/tid=CUSA00572_00
