[XBA would like to thank Skillet for this Roadmap]
|Alien in Training||5|
|Complete Level 1-1 of the game.||(3)|
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.||(2)|
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.
|Head bite 50 enemies without touching the ground or firing.||(14)|
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.||(2)|
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.||(4)|
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.||(2)|
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.
|Reach 5000 Km in Super Soviet Missile Mastar.||(6)|
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.
