Was finally able to beat Level 9 challenge stage... used a combo of Sawn-off shotgun, machete, molotov... IT IS NOT EASY... BUT the trick is to keep everyone pushed back and in the flames... cant let any of those sprinters through

i think its impossible to complete the challenge mode on level 9... i have beat everything else but this... the combination of regen + health buff way too hard... even with all buffs
