Kane & Lynch 2: Dog Days - Extreme Run

So, I finished all the achievement for Arcade Mode in the past 3 days and I have to say the Arcade Mode is quite fun. You can be a good guy(teamwork) or bad guy(grab all the money out). Lightning looter is the achievement you have to finish 2 rounds with $4,000,000 every time(maximum for a round you can grab). So you have no doubt need to be a bad guy and kill all your teammates and kill all the police to escape, which give you some difficulty to leave. But the first 2 rounds is quite easy so not very hard to attempt this one on the bridge stage. More Round and the thing will become harder and harder, enemy will harder to kill but at the same time you can be killed in few shots. By far my best is to round 18 in Airport but I haven't grab money and already need to escape to make thing easier lol.. Right now I am aiming this achievement in Extreme(hardcore) difficulty, and it is a lot harder... - You can die easily in few shots but your enemy take a lot more bullet to die,...
