Event Description

2016

We didn't see it coming. The reduction in budgets for NASA and space exploration meant that we took our eyes off the cosmos. The result was the aliens were able to sneak into orbit and launch a stealth attack on Earth!
"We will not vanish without a fight! We're going to live on! We're going to survive! Today we celebrate our Alien Invasion Day!"

2017

Those aliens never learn! The giant alien motherships hover into view above the freshly repainted White House, Eiffel Tower, and Big Ben. The builders in each country collectively sigh and start collecting their tools again.

At last, the thrilling sequel to last year's Alien Invasion Day event! This year's event adds two new Crusaders (Slisiblyp, the Alien Scientist and Red, the Ace Pilot) along with three other tier 2 chest objectives. Will these new Crusaders find a home in your formation, or will you banish them to the bench-cosmos? The event runs until July 4th at noon PDT, at which point Will Smith and Jeff Goldblum will show up and blow it away. Oh well.

2018

Alien war. Alien war never changes. As massive motherships once again occupy our skies, it's time to take the fight to these alien overlords and cancel the apocalypse.

Those pesky aliens are creatures of habit. They're back again, with even bigger guns! Enlist the aid of a new Crusader, First Lady Betty Smithsonian, and send those cosmic conquerors packing.

2019

It's time to get botanical, with Tier 4 of Gardeners of the Galaxy! Come along for a stroll through the star-boretum, completing 5 new objectives and unlocking a thoroughly pleasant new Crusader.

You fought on the beaches, you fought on the landing grounds, you fought in the fields and the streets, you fought them in the hills, and you never surrendered...

Now, a fourth invasion has begun, here to annihilate the Crusaders and all they hold dear. But you're not alone, dear Crusaders — another alien has joined your forces! Xygallix, the Alien Mechanic is here to help you rally against Alien Invasion 4!

2020

"Today, in the most dire of times, we Crusaders choose not only to believe in ourselves, but in each other. Today we face the aliens at our doors once again. Today, we take the fight to them. No Crusader stands alone. Today, we cancel another apocalypse." ~President Billy Smithsonian

Despite their far-flung origins, the aliens are nice about adhering to an Earth-year schedule. They've come around for another little brawl, and brought some fun new stuff for you. Battle through 5 new objectives to win a cool new Crusader and a fun new look for Billy!
This event runs until July 15th, when the aliens will dutifully depart. Apologies for a late event launch!

2021

"Today, in the most dire of times, we Crusaders choose not only to believe in ourselves, but in each other. Today we face the aliens at our doors once again. Today, we take the fight to them. No Crusader stands alone. Today, we cancel another apocalypse." ~President Billy Smithsonian

Another year, another intergalactic invasion. Most were not prepared and will not survive, but thankfully your Crusaders were on high alert. Rumor has it that some of the alien tech might be quite useful in your own adventures... Take on 5 new objectives to recruit a sympathetic invader and a new skin for Queen Ysorgnak!
This event runs until July 6th, when the aliens will return home.

New Crusaders

Tier 1

President Billy Smithsonian

The first recruitable Crusader for this event is President Billy Smithsonian, the leader of the free world. At level 50, his 'Act of Congress' ability gives a chance for monsters to drop two quest items at once, or count as two kills.

Kizlblyp, the Alien Traitor

The second recruitable Crusader for this event is Kizlblyp, the Alien Traitor. One plucky, smart-talking Navy pilot has managed to outmanoeuvre the extraterrestrial invaders. His wise-cracking aerial acrobatics enabled him to take down and capture an alien called Kizlyblyp (humans are unable to pronounce his real name without spontaneously haemorrhaging their brain. It's a thing.)

Tier 2

Slisiblyp, the Alien Scientist

Kizlblyp has inspired another Crusader to leave Team Alien. Slisibyp, the Alien Scientist, has decided that joining the Crusaders will provide better opportunities for human experimentation. Once recruited, Slisblyp unlocks Symbiosis which enables her to absorb 15% of non-adjacent heroes DPS and convert it to Click Damage. At level 300, her ability Slimy makes clicked enemies move slower for 5 seconds which is renewed for each click.

Red, the Ace Pilot

The second new Tier 2 Crusader is Red, the Ace Pilot, an awesome support Crusader who can provide cover for the Crusaders in front of her.

At level 50, Red unlocks Cover; her ability increases damage done against enemies who are attacking Crusaders adjacent to or in front of her by 25%. Red unlocks Call for Backup which increases the effect of Cover by 25% for each enemy attacking her (additive for each attacking enemy, then multiplicative with the effect of Cover).

Tier 3

First Lady Betty Smithsonian

First Lady Betty Smithsonian is a badass human Crusader buffer. Nobody can motivate troops or empower Crusader behaviour quite like her. The magnitude of her buff is increased by having certain tags in the formation.

At level 100, Rally the Troops increases the DPS of other humans next to the First Lady, and this bonus is increase by her other abilities (such as Human Will) for humans, females, and support Crusaders in the formation.

Tier 4

Xygallix

When the fate of the world is at stake, the Crusaders need all the help they can get — luckily, Xygallix, the Alien Mechanic is here to Support the Formation!

Xygallix is here to increase Global DPS in every way possible. Peace Bribe and Machine Language will increase the damage of your Formation. New Friends will buff all the non-Alien Crusaders in your formation. We Can Rebuild It increases the Gold Find and DPS of your formation based on the amount of Robot Crusaders in the formation, but at the cost of their health.

With Fleet Tactics, Xygallix will buff the DPS of all Crusaders, based upon the number of crusaders within two formation slots of Xygallix. Finally, Xygallix's Hourly Rate ability allows you to buy Global DPS upgrades indefinitely — though the price increases with each purchase.

You know, because mechanics always cost more than you think they will. We know, it's a bad joke ;)

Tier 5

Queen Ysjorgnak

Little is known of Queen Ysjorgnak. She is the monarch at the head of a vast interstellar civilization. Legends say that the Queen was augmented after suffering mortal wounds in a battle at some distant star, and that now much of her body has been replaced by cybernetic enhancements. She is now as much artificial as she is organic...

Tier 6

Qadir of House Tintahal

A bright flash appears in the night sky, giving a purple glow to the surroundings. Those who are awake--and not plugged into their phones--note the curious phenomenon and wonder what they should do about it...and then they forget.

The next morning, the ruler of their country is on the official broadcast channel, introducing the ambassador Qadir of House Tintahal, from the planet Dellorarsvetu, here to observe their new galactic neighbours and get to know them a little bit. (And maybe scout out their treasures.) As the Crusaders are such an eclectic concave of bodies, Qadir elects to tag along on their adventures as well, looking for new energy to taste.
