Game Introduction – Citizen Grim

Citizen Grim is an adventure game developed by Eruptive Games. In this game you will have to survive the masses of Reapers in the post-apocalyptic world of GRIM. Gamezebo’s quick start strategy guide will provide you with detailed images, tips, information, and hints on how to play your best game.

Quick Start Guide

Getting Started

  • Citizen Grim can be downloaded by clicking the “Play Now!” option at the top of this page.
  • When you first fire the game up, you’ll be asked if you want to receive push notifications. You won’t be able to change this setting later. [Note: this step may change as the game migrates to systems that don’t use Push.]
  • After choosing, you’ll be taken to the game’s main menu. Here you can check on the games you’re currently involved in, along with whether or not it’s your turn.
  • When you start Citizen Grim, one of the few survivors aroundwill ask you for your help and walk you through a short tutorial to explain the basics of Citizen Grim.

 Citizen Grim basics

  • Citizen Grim has two gameplay phases: the ‘town phase’, and the ‘attack phase’. The town phase is a moment of peace; there are no Reapers there to attack you, and you can do whatever you want in peace: build and maintain resource buildings, recover from attacks, search abandonded buildings, hire mercenaries and hunt boars and rats. All this can also be done in the attack phase, but obviously you will have other things to worry about then.

  • When you’re prepaired to take on the Reapers, click the red Wave-button in the top center of your screen to trigger the first wave. By clicking the button another time, it is possible to stack waves.
  • This is especially useful if you have a timed mission, or if you simply don’t want to wait around for more Reapers to appear.

  • Resources are vital to your survival in Citizen Grim, so make sure that you never run out. Resources can be found when searching abandonded buildings, they can be generated from resources buildings, and at times they will be dropped by enemies, so keep a look out for them.
  • Bullets: While there are melee weapons available in Citizen Grim, most players will prefer a good old gun as their method to put down those pesky Reapers. The downside to guns is of course that they use bullets, so you want to make sure you always have a healthy amount of lead available before you take on wave after wave of Reapers.

  • Health packs: No matter how good a sharpshooter you are, there will be times when you’ve been hurt so bad that you’re almost dead. When that happens, click on the red cross health-icon to refill your health and keep fighting.

  • Energy: Energy is used for actions such as searching buildings, picking up special items, and certain mission actions. There is only a limited amount of energy you can hold at the same time, but energy refills one point every 5 minutes. As there are few things you really need energy for, it’s best use is to search buildings whenever you have energy available, unless a mission requires the use of energy of course.


  • In the town, there are several empty lots where you can build buildings which generate resources. You can build an Army Surplus to generate bullets, a Pharmacy to generate health packs, a Bank to generate coins or a Grocery store to generate energy.

  •  When Reapers are given enough time to attack a building, it will be destroyed, and you have to click on it (and pay coins) to repair it. If you see that a building is badly damaged, you can also choose to prematurely repair it, so that you won’t be caught empty-handed in the middle of battle.
  •  You can also build one of several types of walls around a building, which will protect it from Reapers for a longer time. When a building is destroyed and repaired, the wall will also be repaired, even if sometimes it appears not to show up.


  • There are two main types of weapons available in Citizen Grim: melee weapons and guns. Melee weapons are generally stronger with each hit, but are slower and as they require you to get close to enemies, there is more risk in using melee weapons. Guns offer the safety of distance to your enemies, but do less damage per hit, and use up bullets.
  • By clicking on the weapon button next to your icon, at the bottom of your screen, you can switch between your selected melee weapon and gun.

Citizen Grim

  •  If you want to switch the weapons you have, for instance a shotgun for a machine gun, click on your icon and go the inventory to select which gear you’re bringing into battle. You can even do this in the middle of a wave; the game will pauze for you. Try the different weapons to see how they handle, i.e. the faster machine gun or the more powerful shotgun, and which weapon best suits your style.

Citizen Grim

  • Every now and then, a special weapon will appear in your town for you to try. You can try it, free of charge, for a limited time and see for yourself how awesome it is. After the time is over, it will stop working, but you will be given the chance to buy this weapon and further improve your chances of survival.

 Weapon tips:

  • Keep an eye out for unlocking and purchasing new and better weapons as you progress.
  • If you’re planning for a stint of many waves, consider using a melee weapon for the first, easier, waves. This saves you bullets you can use for later.
  • Sometimes, when it’s crowded, it can be hard to shoot an explosive barrel, even if you’re standing next to it. I find that in such cases, switching to a melee weapon to hit the barrel makes it easier to get it to explode.


  • If you want to survive in a post-apocalyptic world full of hungry monsters, it’s always good to have someone to watch your back. Come in mercenaries, professional gun men that will fight the hordes of reapers alongside you, for the right price…
  • Once you’ve hired a mercenary, they will stay with you for as long as you can keep them alive. If you’re fighting with a mercenary, make sure you keep some energy to revive them, as even the biggest badass can succumb to the bloodthirsty Reapers.
  • Like with weapons, every now and then a mercenary will offer his services for free, for a limited time. While you can try them at any them, it is best not to waste this precious trial time on the easier waves, so save them for when the big Reapers come out.

  • In the bottom left corner of your screen, there are icons that indicate the available and active missions. The very top icon is the boss of the region you’re in; click on it to check how many more storyline missions you need to complete before facing him. The second icon is always the storyline mission; complete these to progress the story. Every icon under that is a, optional, side mission, which you can complete to earn experience points, coins, and sometimes special weapons such as grenades.

  •  Side missions are activated as soon as you click on the icon. Doing this will show you the objective, the reward, and if applicable, the time you have to complete the mission. If you don’t complete a mission in time, you can just restart it as soon as time runs out, but only as long as you’re still in the game.

 Mission tips

  • There are a few different side missions, which have the same outline but different details. For instance, you can be asked to survive 6 waves or 8, kill 75 reapers or 50 grabbers, or get a 20- or 40-kill streak. Examples include:
  • Kill streak – “Get kills without being hit”
  • Use a gun, and keep your distance, is what will help you get a big kill streak. If you’re in danger of being swarmed, or Reapers are getting uncomfortably close, just run away to a safe distance and shoot them from over there.
  • Reaper hunter – “Kill a certain amount of a certain type of Reaper”
  • Kill an indicated amount of an indicated type of Reaper. It doesn’t matter how you kill them, if you die in the process, or if you complete the challenge over multiple waves; as long as you get the total amount of kills within the alotted time.
  • Wave challenge – “Complete the wave without becoming incapacitated”
  • Make it to the indicated wave without dying. If you do die, the counter will be reset to 1 and you’ll have to try again, within the time set for the challenge. You are allowed to revive yourself with a shot of adrenaline to complete these challenges.
  • Survivalist – “Beat waves by killing enemies”
  • The goal here is not to make it to a certain wave, but simply to complete the indicated amount of waves in the time set for the challenge. If you die, just start another wave and it will add up until you’ve reached your goal. If you’re having trouble completing a survivalist challenge, simply take on the easy waves repeatedly, then die in a harder wave, and start stacking the easy waves again.
  • Final score – “Earn a certain amount of points”
  • Similar to the wave challenge, but here it is the number of points that count (the yellow number right next to the wave counter at the top of your screen). This mission is only considered completed when you’ve died (and see your score at the end), so if you want to complete this mission, make sure you die before the time runs out.

Types of enemies

  • The world of GRIM is overrun by the zombie-like Reapers, but they are not your only concern. There are others roaming the streets, that also mean you harm; the more waves you get in, the bigger the enemies you’ll encounter:

  • Wanderers (introduced in wave 1)
    Your standard type of enemy. Not very fast or very strong, but they have power in numbers.
  • Feral Reaper (a few introduced in wave 2, many appear from wave 3 on)
    Running on their hands and feet like animals, they are very fast. Watch your back!
  • Grabber (introduced in wave 5)
    Bigger and stronger Reapers.
  • Punk (introduced in wave 6)
    Other human survivors that have lost their mind and attack you with guns. Take them out when you see them, or their bullets will keep harming you.
  • Gorilla (introduced in wave 8)
    They’re sometimes called brutes for good reason: they’re big, they’re strong, and they smash anything in their way. Be careful for their ground smash, which throws a rock in your direction.
  • Spiker (introduced in wave 9)
    These big reapers are not only very strong, but they should spikes from their back that seriously hurt. Keep at a safe distance all around this monster when he gets ready to shoot his spikes.
  • Rats and Boars (always present)
    Not enemies per se, in the sense that they can’t hurt you, but shooting them will gain you points.

 Note: If you stack waves, it is possible that certain enemies will appear one or sometimes two waves sooner then described.


General tips

  • If you’re trying for a high score, try to gauge how many bullets you usually use through how many waves, and make sure you stack up on plenty of bullets to make sure you can make it to the end.
  • Here’s a trick if you’re running dangerously low on bullets or health packs. By the end of a wave, leave just one or two Reapers alive for as long as it takes for your buildings to restock what you need. There is no time limit to this, so if you’re really stuck, restock as much as you need.
  • Even if you don’t really have time to play, it always pays to quickly start the game and collect the resources from your buildings when you’re around on Facebook.
