    The fifth mission is "Floodgate". The easiest way to unlock this achievement is to play the level on Normal difficulty with a few skulls turned on.

    First and foremost, play with the "Catch" skull turned on. You only fight flood enemies in this level, and the flood don't throw grenades. Be wary though, because your elite allies will throw lots of grenades and they could end up killing you instead.

    I would also recommend turning on "Tough Luck", "Fog", and "Famine". They will give your score multipliers but won't make completing the level much harder.

    Try to stick to using the battle rifle for most of the level and use it to headshot the flood. Getting a headshot gives you a medal and will give you more points for the kill. At the beginning of the level, be sure to pick up the gravity hammer lying behind an upturned truck. Save it for when you're in tight situations or when you are out of battle rifle ammo.

    NOTE: This achievement can also be unlocked in coop, but you still must score over 15,000 individually. Turn on Free For All scoring instead of Team scoring to be able to see how many points you yourself have while playing the level.

    XystraBonus + for not just being a copy-paste from all the other score achievements. Your tip about the grenades confirmed my thought on it going in.

    Moe GZI played in normal with 4 skulls from the solution, died several times, and my second account died once, so I lost time and reached the end in 22:52, but still won it on first try. This is really doable.

    An important thing to note is that your score during the game includes your skull multipliers. So the only thing you will get at the end of the game in addition is the time bonus.

    So if you have lost a great deal of your time bonus, then don't continue to play the level thinking there is more bonuses at the end, because there is not.

    It is your style of play that determines the skulls you activate. My best advice is to play on Normal. The reasoning behind this is that where Legendary will net you points, you have a better chance of hitting the time bonus on Normal, and you can have more skulls on at once and it still will not be a big deal. Thus more bonus points.

    Start with three or four skulls on, and see how you do? If it is too hard, then start over and remove a skull.

    One the other hand, if you can net the required amount of points, then the time means nothing. On Tsavo Highway for instance, I hit the 15,000 points in game. So I just jumped in a ghost and skiddaddled to the end (running through the rest of the action), and got the achievement.

    And don't be afraid to die a few times, on Normal you don't lose that many points. Of course on Normal you shouldn't die all that much either. Time is the biggest bonus, try for that before you waste time lining up every headshot and multi-kill.

    Good Luck!

    For this achievement you'll need to earn at least 15,000 scoring points on the fifth mission of the Campaign, Floodgate. This can be done solo or with a few buddies. (I got all mine solo and using the method below)

    First you'll need to enable either Free-For-All or cooperative scoring from the campaign options. Then select the following for quickest results:

    Normal Difficulty
    Catch Skull - (1.00 multiplier)
    Fog Skull - (1.00 Multiplier)
    Famine Skull - (1.00 Multiplier)

    So you'll be playing on Normal difficulty with enemies chucking nades alot, no Mini-Map, and ammo pick-ups are scarce. However, being on Normal difficulty will make this a cakewalk. And having these 3 skulls on will start your kill scoring at a x3 Multiplier, so as long as you finish the mission within a reasonable time, and die little-to-no times you'll have more than enough points to pop your achievement!
