Alien Hominid HD isn't an overly hard game to complete. There are a few achievements that could take several tries to earn. The game would be easier if it wasn't for the "WMD" and "Head Chomper" achievements which can be tough and time consuming.

Welcome to Alien Hominid HD! A rather fun game, Alien Hominid will require at least 1 playthrough plus the playing of two or three levels or mini games to collect all of the achievements. There are no cheats to help you out, either.

Abbreviated Walkthrough:
When earning the campaign achievements, it's best to start playing on the Easy difficulty. The two achievements for completing the game on the Medium and Hard difficulties can be earned by replaying the final boss fight on either of those difficulties for their respective achievements. Playing on Easy will also make earning some of the other achievements slightly easier.

Some achievements will come through natural game progression. Like the first achievement "Alien in Training". From the start of the first level, you should destroy every building that you see so you don't have to go back and try for your "City Destroyer" achievement. You'll unlock it when you destroy your 25th building. When you reach level 2-2, be sure to eat 50 KGB agents for your "Hungry Yeti" achievement. If you can survive in one game long enough, you'll earn your "Killing Spree" achievement and using a guide, you can unlock most of the hats for the "Mad Hatter" achievement. You won't have it at the end of your first game as some hats require playing certain levels on different difficulties to unlock them. The "Head Chomper" achievement is best left until after you complete the game as you can die very easily while attempting it.

When you're finished with your first playthrough, simply re-load the final boss fight on the Medium and Hard difficulties for the "Adult Alien" and "Expert Alien" achievements. Now is also the time to re-play any missions on different difficulties for the hats that you need to unlock Mad Hatter.

Once all of your other achievements are completed, the only ones that should be left are "WMD" and "Survivalist". Since you should now have all of the mini-games unlocked, you can follow the guide on the best way to earn those achievements.

Without a doubt, the hardest achievements in the game are "Head Chomper" and "Expert Alien". With some practice and a little luck however, you should be able to earn them. If you missed any achievements, simply follow the achievement guide and re-load the level where the achievement can be unlocked.

There are 12 achievements with a total of 200 points

  • Complete Level 1-1 of the game.

    You simply need to finish the tutorial level of the game. The achievement will unlock after you defeat the iron juggernaut. If you’re having difficulty with this achievement, then switch to an easier difficulty as it’s only going to get harder. This achievement will unlock through natural progression of the game.

  • Eat 50 KGB Agents with the Yeti.

    You’ll meet the Yeti during Russia during 2-2. He’ll be chained to 2 stumps and you have to free him to use him. If you stand in the one position there will be a constant swarm of enemies attacking you and eventually you’ll get the achievement. Make sure you eat the 50 KGB Agents before the tenth sentry-tower as the Yeti will arrive at a cliff and you won’t be able to use him anymore.

  • Destroy 25 buildings during one game.


    It takes 3 grenades to destroy the one building. On easy you’ll start with 7 grenades, medium you’ll start with 5 grenades and on hard, 3. This is not during the one level, it’s the entire game. If you gain any power-ups from fat kids then you’ll get some extra grenades so take any power-ups you can find.

  • Complete the Game on Easy Difficulty.


    This is a story related achievement, which will unlock after you have finished the game on the easy difficulty. If you are stuck, please refer to "Expert Alien".

  • Complete Game on Medium Difficulty.


    This is a story related achievement, which will unlock after you have finished the game on the medium difficulty. If you are stuck, please refer to "Expert Alien".

  • Complete the Game on Hard Difficulty.


    This achievement is a lot easier than it sounds. Instead of finishing the entire game on the hard difficulty which sounds daunting, you can simply finish the final boss on hard.

    If the final boss is too much of a challenge for you, grab a spare controller and set it on easy. Once you enter, quit with the spare controller and restart the level. Fight the boss with the spare controller until his health is pretty low and then – when on the verge of death – sign in with the controller you want to get the achievement with and defeat the boss. You’ll need to die with the spare controller before you defeat the final boss or it will register him as being easy.

  • Head bite 50 enemies without touching the ground or firing.

    This achievement is probably the hardest in the game, due to the fact it’s nearly impossible to continuously head-chomp without touching the ground or firing. To jump onto someone’s head you have to press and then when you are directly above them, press again and you’ll sit on his shoulders. Press to bite his head off.

  • Kill 1000 enemies during one game.

    This is not during the one level, it’s the entire game. You can either stay in level 1-1 and continuously the never-ending Agent horde or you can simply play through the game. It takes one bullet to kill an enemy, excluding bosses, vultures and scorpions. If you’re having difficulty with this achievement, then switch to an easier difficulty.

  • Unlock all of the 31 hats that are in the game.


    Follow this [CLICK] collectible guide to attain all the hats.

  • Defeat the Final Boss without using a continue.

    Refer to the second paragraph of "Expert Alien". It show’s you a trick you can use to easily defeat the final boss.

  • Survive any challenge mode for 20 minutes.

    This achievement is easier than it looks; you’re going to want to do the Urban Challenge as it’s really easy. It’s just like the road mission from the first third of the game; you’re going to need to hop into car after car for 20 minutes. If you hold you’ll charge up your gun, so whenever an FBI agent’s car arrives you can instantly destroy it.

  • WMD



    Reach 5000 Km in Super Soviet Missile Mastar.

    Just follow my route in the video and you should complete it with ease.

    Planes can only go a constant speed in the horizontal direction.
    Helicopters can only go a constant speed in the vertical direction.
    Brids are a mixture of both, they move up and down while maintaining a constant speed.
