How to unlock the "My vodka is better" achievement

Easy and simple guide to unlock the "My vodka is better" achievement for which you need to make two Vodka guys fight each other.

I am not the brain behind the strategy behind this guide. It was Seriousharry whom I asked in a discussion how he unlocked the achievements. So all credits go to him. I just wanted to share this with everyone since I couldn't find a guide on Steam or anywhere else in the internet. Thank you again Seriousharry.

With the following instructions, I could unlock this achievement myself at first try, so it shouldn't be too difficult for you too. It's not as hard as it sounds actually.

Requirements and Basics

Before you can start attempting to unlock this achievement, you need to have beaten the game in order to unlock the "Download Level +" mode in which you have all the characters unlocked and you can select the level.

The best level to unlock this achievement is Level 24:
1. Enough Vodka guys appear, so you have a very good chance to get at least two Vodka guys on one lane (I had three such lanes)
2. There aren't too many enemies like on higher levels (but enough vodka guys), so you don't struggle much fighting and it's easier for your strategy

The essential two characters you need are Pimp and Fatman:
Pimp --> obviously you need to hypnotize a Vodka guy in order to make him fight the other Vodka guy
Fatman* --> to protect and lock the vodka guy in till the other guy comes
*(not "The Fatman" which is more expensive and attacks the enemies, I mean the cheaper one which is only called "Fatman")

So you basically chose Level 24+ in the Download Level+ mode. You buy Pimps, Fatmans and other fighters. I chose Kendrick, Capitalist, Ronald and Trap.

Keeping the first Vodka guy busy

Here's the main strategy:
As soon as you see the first Vodka guy appear on the right side of the screen, you wait till your fighters kill everyone in front of him. When the other guys are killed and the Vodka guy is first on the lane, you immediately delete your fighters with the hammer on the bottom right corner of the screen, to prevent the Vodka guy from being killed. You need him later. Obviously.
Now you put a Fatman on the second spot of the lane to keep the vodka guy busy, till the other guy comes. On the first spot (on the far left) you put a Pimp. The lane should look like this:
#1[Pimp]--#2[Fatman]--#3[Vodka guy]--...

Waiting for the second guy

Now you have to wait for the second guy. Put a fighter (like Kendrick) right behind the Vodka guy to kill everyone else incoming.
#1[Pimp]--#2[Fatman]--#3[Vodka guy]--#4[Kendrick]--...

When there are too many enemies coming, you can use Ronald or Trap too. Be careful with Ronald, as the second Vodka guy might appear and you accidentally kill him too.

Locking the first guy in and keeping the second busy

When the second Vodka guy appears on the right side of the screen, you kill the guys in front of him again and delete Kendrick as soon as the Vodka guy starts being attacked. Put another Fatman on Kendrick's spot.
If necessary, you can put a defender/Kendrick behind the second Vodka guy again if there are more enemies coming. I didn't need that since it was close to the end of the level and there weren't any more enemies coming on this lane (check the remaining enemies counter on the top right corner).
The lane finally should look like this:
#1[Pimp]--#2[Fatman]--#3[Vodka guy]--#4[Fatman]--#5[Vodka guy]--...

Waiting for the success

Since you can't delete your defenders while they're being attacked, the only thing you need to do now is wait till the first Vodka guy beats the first Fatman. This will logically happen earlier than the defeat of the second Fatman, since the first Fatman is being attacked longer.
You'll see how the first Fatman dies, the Pimp hypnotizes the first Vodka guy, the Vodka guy turns around and starts attacking the other Vodka guy. You don't need to wait for the second Fatman to die, because the hypnotized Vodka guy will walk straight through him. As soon as he makes the first hit, the achievement unlocks.

Good luck and congrats

Best of luck for anyone trying to unlock this achievement and congrats to those who did it.

You can ask me about any other achievement and what you need to do to unlock them, since there are some hidden achievements and some of them have unclear hints on them. If instructions should be unclear, ask me again and I try to explain better. If that doesn't help, I might do this again and put screenshots in here.
