Shout out to Death and Glory for the guide

I did this in my video Achievement Walkthrough at 7:45

So a recent patch came out that fixed the Booster Shot achievement but I could still not get Lockdown to work. I tweeted out to Blowfish Studios and they told me you have to chain kill 4 towers with one hex, not just get 4 towers inside the hex circle. This still confused me since the Hex curse doesn't actually do damage, so I experimented a bit. This is what I managed to figure out.

One of the perks of the Hex curse is that it spreads to the next tower when the leading cursed tower is destroyed. The way I got the achievement to pop was to push out 4 outposts in a straight line on player 2. Then with my main account, I set up a few outposts and shot kegs at the towers. I destroyed the leading tower and worked down the line until I destroyed 4, then that magical achievement unlocked sound rang. Whenever the curse spreads to the next tower, the duration of the curse is reset so you should have plenty of time to destroy each consecutively.
