Rabbids: Party of Legends

This is a rather tough one and probably one that you'll need to replay in Party Play (it unlocks at level 15). This long explaination is a full guide offered for people having difficulty unlocking the achievement.

The best strategy for this level is understanding how it works because it gets very messy and hard to follow.

Simple guide:

First of all you have five lives represented by hearts, each time you come into contact with an electrified ghost you will lose a heart. The objective is to survive longer than other players

There is one ghost at first and electric blue circle shows appears to show where they will drop in, you need to try to avoid this and push to throw other players towards it so that when she spawns they lose health. They will start to multiply until they cover the whole map, and the electric circle will randomly spawn on single ghosts, try to avoid them and occasionally hit opponents until they have no health.

Troubleshooting guide:

I have tried playing this safe on the sidelines (which works well for variants of this level in this game), here the problem is more and more ghosts spawn in making the level more and more chaotic as the game goes on. The best strategy is to get in early while it's still safe and do as much damage as you can.

Once the other ghosts start spawning in try you best to keep an eye on the electric blue circle, it will choose a ghost at random to become the damager, the other ghosts will try to crowd round you so that you cannot move. At this stage you should mostly be focused on surviving, you will probably have one or two other players out of the game now but they appear in the level still in a full player colour (all yellow, for example) and wonder around confusing you. You really need to cut through the visual noise and focus on avoiding being backed into a corner (which seems inevitable eventually). At this final stage it becomes a bit RNG as you and the last standing player will likely be surrounded by ghosts and both of you with low health and the game will choose which of you will get zapped.

You may have to redo the game a few times (as did I) but eventually luck will be in your favour if you follow these steps.

Glitch:

If, after the game, you find that you have earned more than 5750 and the achievement hasn't popped, wait about 15-30 seconds as it could be late (as mine was) then if nothing appears yet many players (including myself) found that rebooting the Xbox results in the achievement(s) popping on the dash after starting up. You should be aware that the timestamp is for when the achievement pops and not when you earned it. Additionally, if you have several achievements that are waiting to pop then they will all at the same time and will share the same timestamp.
