Let Them Come – 100% Achievement Guide

This is a guide to help with understanding how achievements in this game can be achieved, some are common sense but some can be done in easier ways.

How to Obtain All Achievements

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 grenades

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.

Unmissable Achievements

Game Changer

  • Thank you for your support!

Achieved by opening the game.

Combat Ready

  • You completed the game tutorial.

Yes.

Perfect Bonus

  • Perfect combo bonus!

When the combo meter fills up, you will have to correctly time the filling up of whatever bonus you get. Achieved by perfectly filling it, not late, not early.

Trophy Hunter

  • 100 Enemies Killed!

Self explanatory.

Bone Collector

  • 1000 Enemies Killed!

Self explanatory.

Exterminator

  • 5000 Enemies Killed!

Self explanatory.

Annihilation

  • 10 000 Enemies Killed!

Self explanatory. But you could finish the campaign without getting this one, you can still play new game plus or challenges to kill more baddies.

M-M-M-Monster Kill!

  • You killed 10 enemies at once!

Easily gotten with explosive bullets later on in the game or by exploding swarms of flying or crawling enemies early on.

Grindy Achievements
