If you can get 1.75 you can get 3. I got 3 easy mode. Get the 400k golden gun. along with about 40 nukes. Shot him and as soon as he's coming down shoot him back up. (4 times) then use a couple bombs. When he starts moving slower distance wise and just going high, use his jet pack, shoot him 6 times. Then just keep using bombs. Have a chest bomb just in case. and get him low on the ground and try to get some more ammo. The key to getting 3m is in the ammo. If he's about to stop moving use and nuclear bomb.
