This will require you to be on co-op mode, but take note that it requires you to be online. And you will need to kill 100 orange targeted enemies (the other ones do not count towards this achievement). But getting this is very hard, let alone a very few people who are attempting to getting a full 200G or less each year!

If you're going for this achievement (along with Like taking candy from a baby), you might want to find a person who hasn't got this yet (either here or 360A); if found a boosting partner, take turns and share the kills. However, if you can't find someone, let me know by PM here or XBL.

Update: If you happened to scored some orange targeted kills but you have been disconnected due to lag, your stats will be saved. The leaderboards are rather bugged, making it hard to tell what's the actual kills you have. In other words, just keep playing until the achievement pops.

So I'm just going to get to the point. This achievement is known to be glitchy.

In order to get it, you have to defeat 100 Boss Monsters whilst playing online Co-Op.
The Boss Monsters are the ones that have a Orange Target indicated on your screen, to where they are known to be hiding. The amont you get depends upon the level your playing in. As you progress in the campaign you are doing, more Boss Monsters will appear, giving you more kill progression towards this related achievement.

You can have up to 4 people playing Co-Op with you at the same time. But only one person will claim a kill when the final shot on the monster is directly hit on them. For that reason I recommend finding a partner to help you out with the game, or just bring in a dummy account and keep them idle throughout the duration. I pearsonally chose the latter as the game is Backward Compatible on the XBox One and I used the Share With Gold feature to get my dummy account to boost the game with me.

Among all the campaigns you can choose from to play Co-Op, I recommend sticking with "New York", as that has the easiest Boss Monsters to defeat. Tokyo has a Monster has 2 Stages before it can be defeated, which alone can be a daunting monster to kill (it is kind of a robot). And Paris has a Monster that can only be shot in one area on it's body (giving more work for the user).

At times, whilst you play the campaign in Co-Op, you may notice on your screen a pop-up will say "Help". This means you, or one of your partners is in trouble, so if you can, try and find them to assist their needs in getting rid of a monster, as leaving them to suffer will cost a life and then they may not be able to respawn back into the game with you, until you have lost all your lives, or the level is complete.
If you are playing this with a dummy account, consider seeing that Help word quite a few times, late into the campaign.

You can check your progress by going to Leaderboards, then scrolling to find "Most Kills".
Now here is why I say the achievement is glitchy. According to the Leaderboard, when I had 100 Kills, I didn't get the achievement. I ended up getting the achievement at 133 KIlls. The only thing I done differently was test the Tokyo & Paris Campaigns once to see if they we're easier to beat than New York. There I killed the Boss Monsters a few times that we're lurking about. These monsters that I killed must have not counted towards the achievement, because I believe once you have picked a certain Boss Monster to kill for the first time, that's the only one that would count towards the achievement. Killing the others won't count towards the achievement afterwards.

In the end I played a few more campaigns in New York afterwards and I finally got the achievement when I got 133 Kills claimed on the "Most Kills" Leaderboard.

You will be looking at around 2 - 4 hours of playing the same campaign over and over again before one of you will be getting this achievement (doing it with human partners in Co-Op). I hope you have some time and patience when you decide to go for this achievement.

Good Luck.
