Note: When you play this game mode, only 1 chosen person will be able to go for this achievement per match. And they will need to choose which achievement among the 2 within the DLC they want to go for, as they will only be able to get one in the match. The other achievement they can choose from that is tied to the Frenzy game mode is this one, so choose wisely... The Renaissance Man achievement in Crysis 3 worth 106 pointsGet 2 kills with each weapon in a round of Frenzy (Public Match only)
Frenzy is a game mode in which everyone will be on their own and you will all start with the same weapon. After 60 Seconds, the weapon equipped will change into something else. You have a total of 10 Minutes and the Maximum Score is 10,000 Points.
If you are boosting towards this achievement, this is the easiest one to get among the two in the Frenzy Game Mode. You will need 6 people/accounts in order to start an online match in this game.
All you need to do is get the most kills in the match. It is best done by having 1 person alone, be the dedicated person to get all the kills in the match.
If you are the person doing the killing, find a decent spot on the map that you believe will be easy for everyone else to track you down. Then as soon as you see some opponents, kill them on sight! As you obtain kills, you will get a Multiplyer placed on yourself. Once you get more than 5 Kills without dying, you will have the maximum bonus which is 5x Multiplyer. Not only will this increase your score per kill, but it will also place a 5x Multiplyer on everyone elses screen, indicating where you are. This would make everyone else who is the Bait, easier to find you.
Keep on playing your role as you are for the remainder of the match, until the winning person gets a score of 10,000 Points and Wins the match. Once the match is completed, the achievement should unlock for them. Swap over roles for anyone else who needs the achievement and rinse and repeat until everyone gets the achievement within the group your boosting with.
Depending upon the size of the map, this achievement should only take 5 - 8 Minutes per person, but be-aware that randoms can join your match at anytime if they own the DLC content for the game.
Hope all this helps, good luck!
