Let Them Come – 100% Achievement Guide

Missable Achievements

 
Bonus Fury 
 
2 active bonuses at the same time 
This one is NOT highly missable but can be overlooked if the combo meter upgrade is neglected. You just need to have as the achievement states, 2 active bonuses. Examples would be the drones, 2x multipliers, frenzy, etc. 
 
BONUS MANIA 
 
4 active bonuses at the same time 
This one is NOT highly missable but can be overlooked if the combo meter upgrade is neglected. Similar to the former Bonus Fury but you need 4 at the same time. Just make sure you upgrade the combo meter whenever possible. 
 
Close Quarter Specialist 
 
You completed a wave using only secondary items 
This can easily be done during the earlier levels as it would be hard in the later levels due to the large number of enemies. Make sure to do this near the beginning. 
I personally did this later in the game with the help of a rocket drone and while using the hand cannon, yes bonuses can be used to complete this achievement. 
Granadier 
 
You completed a wave using only genades 
This can easily be done during the earlier levels as it would be hard in the later levels due to the large number of enemies. 
I did this in the early levels with the molotov but is possible to be done later with the help of 
drones, bonuses can also be used to get this achievement. 
 
FRENZIED 
 
You killed 100 enemies in a frenzy! 
This could be quite hard and should be done later into the game. 
I personally got this by using explosive bullets during the stages 100+ on the Highest difficulty campaign (not newgame plus, though i’d say it would be easier in new game plus due to the sheer amount of enemies). 
 
GODLIKE 
 
You finished campaign on highest difficulty 
You can play the whole campaign in the lowest difficulty and set it to max ddifficulty when you reach the final boss.
