Easy to defeat, but a threat in groups. Where did they all come from..?


Fire accurate shots with knockdown. Jump on their shoulders to fly!


Quick moving, attack in swarms by dropping lots of landmines.


Slow, but good at melting poor invaders who forget to not to stand under them.


Beefy agents with huge shields. Get behind them but do not ride!


Extra tough agents with advanced weapons, but they drop extra juice when hit.


These agents looks like robots to me. Or robots disguised as agents maybe? How creepy!


Deployed by vans and skyvans. High damage, rapid fire guns. How do they all fit in there?


Deploys squads of dangerous Shocktroopers. High priority target.


Long-range projectiles create large explosions on contact. Get close.


Create indestructible shields around nearby agents. Try tossing them!


Slow down invaders who get too close. Best to jump on them and throw them away.


Low mobility but high rate of fire. Defeat the pilot to ride it yourself!


Hunt in packs looking for invaders to knock down. Hard to catch, fun to ride.


Hop, hop, hop around so many deadly bubbles! Do they hop for me?


Agents have learned: Invaders can catch on fire! Roll or dig to put it out!


Their shots weigh invaders down. Jump, dig or roll to shake them off.


Watch out! You can see where they’re aiming before they fire.


Flying heavy artillery, Their slow moving shots follow invaders and hit hard.


Deploy Shocktroopers. Watch out for fly-by attacks when invading the sky.


This is the lozenge man. Slowing you down is his lozenge plan. Such good hair.


These robots are confused. Invaders are not trash! Dig to avoid their beam.


Robots with fire breath. Roll or dig to put it out. Do these robots really breathe?


Ambusher. Heat-seeking, high damage attacks. Mama says just do your best.


These are small and also crab? Dive through their beams, but be careful: They hop.


These are large and also crab. Fire clusters of bombs. Ride or blast from a distance.


Ambusher. Even faster than normal inchworms. Shoot them in the face!!


Bounce off walls and smack invaders with their tail. How rude!


Makes hackerbombs like the mothership makes invaders. But does he love them? No.


Get close, they fly closer. Trained to explode near invaders. Dive past or avoid.


These try to escape so they must be important. Stop them! They sometimes drop bombs.


Filled with secrets. These slow down if you shoot them. Mama just thinks they’re neat.


Shoot to push them, but quick invaders can use them as platforms before they explode.


Deadly. Indestructible. Destroy the Keybot to shut them down temporarily.


Destroy them to get past checkpoints. C.H.O.M.P.E.R. loves to chase them.


This planet is usually safe to walk on, so agents invented spikes. Shoot before walking.


You can shoot Bounder to knock him away. He doesn’t mind. He always comes back.


These robots are indestructible and attack in perfect sync. They must practice lots!


Oh, what are these? Did grandma make them?


A robot who thinks she’s better than you. She hates it when invaders stand on her head.


This eyeball is installed in an even stronger brawler. Is it too late to be friends? How sad.


Rebuilt with better mobility and even more firepower. Run away when he spins his arms!


Deadly blade, heat seeking bullets, calls in Miniwasps. Is this what they call “Taking a power trip”?


Mutation juice has a strange effect on agents, no? Juice is best for growing invaders.


This is Mothership’s mothership. Likes to take over and do things her way. We don’t talk much.

These are new enemies and hazards information from the Update Part 2 (Juicy Variety Edition).


A very wide bot with a very serious job. He does not know about the little hat. Hee hee!


These let you miss and still hit your target! Just call it a trick shot (I won't tell).


Mmm, I see. But doesn't that mean... the pinball is you?


When one goes up the other must come down. Shoot one to try it! Isn't science fun??


Walk, jump and now slide? I wish I had legs :( JK! Mothership flies! In space!


This was not a crime of passion. No one brings a spoon that big without having a plan.


Fire heavy weight that slow you down. Jump, dig and roll to shake them off!


Surf these through the skies but watch out for the tip - they explode!


Based on an earth fairytale. Two friends riding a frog to victory! Sigh, I wish frogs was real.

"You can pause in online multiplayer if all players choose to"
– Dan Paladin

The history of our game begins with the creation of our first. With Alien Hominid HD only available on older gaming consoles, this project started with the simple idea of bringing our alien pal to today’s gaming systems. We quickly shifted to the creation of an entirely new game, developed with modern gameplay mechanics and features that highlight the strengths our team has developed since Alien Hominid HD’s release in 2004.

In Alien Hominid Invasion, the alien will now have a health bar instead of the previous title’s one-shot kill mechanic, giving more people the ability to approach the game and fight back against the agents. Players will have much more customization options this time around; the alien’s head, pigment, and gun are equipable from earned loot! Up to four players can join the invasion, with a new functionality allowing participants to play across skill gaps by choosing their own difficulty. Hardcore fans and lore enthusiasts can look forward to learning more about what happened to the original alien, where the agents came from, and why there is such an intense hunt for the aliens.

Looking for more intel on the invasion? Be sure to stay up-to-date with development news and updates on our blog!


Alien Hominid Invasion is a game of many words in very few letters, mostly grunts, shrieks and AAAAAAAHs! One of our favorite parts about creating our games is being allowed to further the world of that game through your ear holes. While audio design is not only incredibly fun for us, the stories and human beings behind these noises are deserving of their own special praise!

CURTAIN CALL!


Not only is Dan the Man with a game(plan), he is the voice behind those anguished, destroyed, sobbing agents that all you alien hominids have been ruthlessly vaporizing since launch. When he’s not fighting for his life as an agent, Dan has been known to draw and make games, along with spending time with his favorite Bulldogzer, Winston.


What would life be without dogs, even if they are robotic and possibly nefarious? Winston Paladin gladly stepped up to the bowl plate when offered one lump sum of “Who’s a good boy? You’re a good boy!” Kenseth Thibideu, our sound designer, and Ian captured Winston’s award-deserving performance by chasing him around our studio with a microphone…The General quite literally trained these bulldogzers himself.


Every time you die and your alien cries for their Mothership, it’s the same voice as our cackling, scheming, long-term nemesis Cyboris (formerly known as Boris…what happened, Boris?)! Ian Moreno has both sides of this intergalactic invasion handled when he’s featured as an agent, with a big WOOOOOOO for his Digestor language translations. Wearing many alien heads hats, Ian served as our producer/audio director on Alien Hominid Invasion, overseeing all facets of auditory production and integration in the game, all while speaking only in Digestor. An impressive feat!


Monica, Megabot, Mothership – a role matched in outer space. Monica Franco brought the Mothership we all know and love to life. When she’s not knitting aliens to life, Monica’s pastimes also include hunting aliens as Megabot. Remember, KILL-IT-FOR-MAMA-KILL-IT-FOR-MAMA-KILL-IT-FOR-MAMA-KILL-IT-FOR-MONICA


As a former self-professed Newgrounds kid, Jeremy “Disguised Toast” Wang lent us his vocal cords to bring our big, bad W.A.S.P. Boss to life. A beloved boss from the original Alien Hominid HD, the W.A.S.P. Boss’s legacy lives on through Toast as the Agency’s bzz-bzz-boss. Keep your eyes peeled for the Disguised Toast unlockable alien head–you have to look for it, since it’s disguised.


Joining the agent lineup is Kenseth Thibideau, our sound designer who helped orchestrate our audio of astronomical attributes. Along with Ian, Kenseth worked diligently on fine tuning weapon clicky-clicks, environmental echoes, and giving our two favorite fated friends voices. Working with a wide array of gadgets and technology of Earthly origins, KT helped create our atmosphere of chaos and extra-terrestrial arsenal of weapons.


Patric Catani is the brains and bapi’s behind the iconic beats for Alien Hominid Invasion. An honorary chicken at this point, Patric has collaborated with us at The Behemoth for quite some time, and jumped at the opportunity when presented with a chaotic sci-fi arcade soundtrack. Utilizing an impressive arsenal of instruments, including a theremin, Commodore 64, SEGA chips, analog synths, instruments and real aliens, (just seeing if you’re following along), Patric has perfected the art of video game soundtrack creation with Alien Hominid Invasion’s OST. Since he created different levels of songs to increase with your level progression, you can hear some sweet sounds if you Kill-It-For-Patric!

Amanda: Community manager, marketer, moderator…SUPER EVIL SURPRISE END BOSS? A quintuple threat, Amanda plugged into the mainframe, picked up her knitting needles, and nearly obliterated the solar system with her performance. In her free time, Amanda does NOT knit, she crochets, and reminds the aliens in the Discord Server to behave. Don’t make her go Grand Mothership.


David brought the agency’s Juiceman to life not only by voicing him, but also by designing and animating him! As the Agency’s final line of defense against layoffs and alien attacks, Juiceman is our favorite boss to hate. Juiceman evolved over time, eventually landing in his final, fluid form as the Vengeance of the Agency. Don’t you feel just a little bit bad for Jim now?
