Siege of Centauri - (Ollie Toms)

To say that Siege of Centauri is one of the most uninspired games I’ve ever played in my life sounds, well, a little harsh. But as I plopped down tower after tower and eviscerated enemy after enemy, I found myself comparing the game to two dozen others that were almost identical in function. And then I thought back to my favourite tower defence games of all time – Plants vs Zombies, They Are Billions, Protolife – and how each of them took the familiar formula in a very new direction. By comparison, Siege of Centauri is stubbornly, brutally> unoriginal with its unwavering mantra of “place down towers, defeat waves, upgrade towers, defeat waves, congratulations, you’ve won, time to do it all again.”

So why, then, has Siege of Centauri just shot up to join these innovators at the top of my “best tower defence games ever” list?


Siege of Centauri - Yarlen
Stardock has released v1.04 of Siege of Centauri today. This small update fixes the following:

  • Fixed an invalid unit on Ulrath
  • Fixed issues that can cause the game to crash on start from:
    • Downloading an invalid scenario
    • If a custom scenario map cant be found
    • If your progress is corrupt

Progress files are now backed up to: \Documents\My Games\Siege of Centauri\Backup to help protect against player loss/corruption.
Siege of Centauri

Games like Plants vs. Zombies, Kingdom Rush, and Orcs Must Die are not the only tower defense games, but they are arguably the poster children for the genre. Apart from They Are Billions, tower defense games tend to have whimsical tones, an aesthetic that can be at odds with what is a surprisingly intense style of game. 

Siege of Centauri brings seriousness and danger to the genre and tonally feels closer to the games that laid the groundwork for tower defense, like StarCraft. But Centauri's gameplay feels closer to something like PixelJunk Monsters, with clearly defined locations for placing your weapons and a straightforward upgrade path as you work your way through the campaign. It's a bit too derivative, even if I still enjoyed blasting endless waves of alien robots.

Siege of Centauri takes place in the universe established by real-time strategy game Ashes of the Singularity. I always appreciate an effort to put multiple disparate games from a single developer under one umbrella, but it adds little to the story in this instance. Every level features a different character offering up a cryptic monologue before each mission about the plight of the location you’re trying to protect and the robots that must be defeated. Some characters return for additional monologues in later levels, but my eyes usually glazed over as I waited to start the fight. In his review of Ashes of the Singularity, Leif Johnson wrote, "The characters are as memorable as the back label of a Hershey's bar," and I can confirm they haven’t grown much in the intervening years.

The plot and characters may be underwhelming, but it doesn t hold back the overall experience.

The plot and characters may be underwhelming, but it doesn’t hold back the overall experience, even if Siege of Centauri doesn’t innovate in any dramatic ways. Before each level you get a chance to survey the various routes the robots will potentially take, see where they will be coming from, and it even gives you a good idea of the kind of robots that will be invading. I appreciate how much information is available before you start, and nothing begins until you place your first weapon so you have plenty of time to figure things out. Nothing is more obnoxious in a tower defense game than having to fight off a unit you don’t understand after you've invested so much time and currency in fighting off something different. All the information and prep time helps to avoid this.

The maps are basically a series of cliff-lined valleys that the enemy robots travel through. Your placement options are at the top of the cliffs with grids appearing to show you where your weapons can be dropped. In general, the grids are substantial and allow you to overload just about every location with powerful, dense pockets of turrets. When you place a gun, it gets a full animation of it being flown in and dropped into position. No sudden, magically appearing weapons here. I especially liked sending in a whole collection of weapons and watching them all get flown in by an army of drone delivery ships.

You can pause the action (though the option runs out if overused) to get more specific with your weapon placement without fear of being overtaken by robots, which is helpful. During the occasions where you’re ahead of the game, you can also speed things up, which I was especially thankful for in the early tutorial missions.

Each level you complete awards you a new weapon, or more tech-focused tools like the Scavenger Module, which helps you gather additional energy to spend more on weapons during the course of battle. You also earn upgrade points that you can use to advance the weapon you already have. I especially enjoyed boosting my Light Rail Gun, the cheapest weapon, as much as possible just so I could fill the battlefield to the brim with defenders.

It was during mission 5, after listening to a robot with five eyes named Milton warn me that the enemy’s strength was increasing, that I was able to put this simple, but effective strategy into practice. The layout of the level only had two points of enemy entry so I dumped all of my currency into my leveled, but simple turrets and overloaded the entrances. Since I was able to buy so many, it was almost comical watching all the delivery drones drop so many turrets into just two locations.

Siege of Centauri plays like a basic tower defense game with many concepts I have used before and it did little to get me excited about what was coming next.

Rushing the waves as my turrets absolutely obliterated the attackers was satisfying and strangely relaxing as I basically had nothing to worry about. A few robots made it through, but I had another "just in case" bounty of turrets set up right near the colony that had no problem with the stragglers. The difficulty ramped up shortly after, that leading to more intense missions and last-second decisions, but I always found new strategies like the one on mission 5 that were fun to execute.

Along with the campaign, which is made up of a collection of dedicated levels, you can also tackle Endless Mode, or scenarios created by others. The Map Editor is expectedly complicated, but having an integrated creator is always a good thing for those who will potentially dive deep into Siege of Centauri and want more.

I probably won’t be one of those people. Siege of Centauri plays like a basic tower defense game with many concepts I have used before and it did little to get me excited about what was coming next. It's a perfectly adequate game. But the serious sci-fi tone is something I don’t typically associate with the genre, so Siege of Centauri at least feels unique in that way.

Siege of Centauri - IslandDog

Communications to Earth's first interstellar colony in Proxima Centauri have gone dark. In response, Earth has dispatched the Carpathia to investigate. Upon arrival, you find a colony under siege. Your mission: save the colony from these brutal alien invaders.

Siege of Centauri puts you in command of the defense of Earth's first interstellar colony. Set in the Ashes of the Singularity universe, thousands of alien machines are attacking and only you, with your arsenal of deployable defense structures and strategic orbital abilities, can stop them.

Customize the Carpathia in order to best handle the challenges of each individual mission, battle across the surface of an alien world through a series of story-driven campaigns, or see how long you can survive in a doomed region where the enemy waves are truly endless.

The enemy comes in all shapes and sizes, challenging you to counter them with the right defense in the right place. Siege of Centauri combines the best elements of classic tower defense games with the strategic depth Stardock has delivered in past titles, including Sins of a Solar Empire: Rebellion and Ashes of the Singularity.

Defend the Colony
Proxima Centauri is under attack from hordes of alien invaders! Play through a vast campaign full of challenging missions. Deploy defenses, use powerful orbital abilities, and call units at the right time and place in order to win.

Create your own Missions 
Use the in-game workshop, then upload and share them with other players. Download new missions created by other users, too. Get started with the Modder's Guide here.

Customize your Defenses
Choose from dozens of tower upgrades and determine what you need in order to survive. Upgrade your particle cannon to slow its target, your Artillery Post to leave fire in areas it has attacks, or your Corrosion Mortars so that victims infect the allies around them. 

Survive the Onslaught
See how long you can survive against relentless enemy waves in Endless Mode! Try to outlast other players and compare your scores on the leaderboards.

Fight against Dozens of Enemies
The alien invaders have many unique attacks and defenses. Beware the Falling Star that disables defenses when it explodes, or the Heart of the Phoenix that forms a chrysalis when destroyed that can be reborn as a new Heart.

Siege of Centauri - [SD] redskittlesonly
Stardock announced a September 12th release date for its take on the tower defense genre, Siege of Centauri, today. Set in the Ashes of the Singularity universe, the player takes on the role of defender of Earth's first colony on Proxima Centauri.

In Siege of Centauri, players defend their colony against relentless waves of thousands of enemies. In the campaign, they will follow the story of Earth’s defenders and progress through increasingly difficult scenarios in their mission to protect the colony at all costs. Dozens of upgrades are available for the defense towers, leaving the player with important decisions regarding how best to equip their defenses on each map.

"With tens of thousands of enemy machines pouring toward your base, we wanted to give players a very new experience of what it means to defend themselves against overwhelming odds," said lead designer Derek Paxton. "In addition, we’ve incorporated several strategic elements into the genre, including defending resources and deploying rapid response teams to battle. Our goal was to provide players with difficult choices about which areas to defend and which areas to let go, leading to greater strategic depth.”

Players can also create their own missions with the Scenario Workshop, then upload them to Steam for others to try.

“It’s always been important for us here at Stardock to put customization into the hands of the players,” said Paxton. “Now, people who have always wanted to design their own tower defense games can create their own maps and missions.” Players can learn more about how to make their own scenarios with the Modder’s Guide.

Siege of Centauri is currently in early access for $14.99 and will release on September 12, 2019. For more information, visit

Beta 3 is now available for the massive-scale tower defense game

Newest update adds scenario workshop, endless mode, and much more

Set in the Ashes of the Singularity universe, Siege of Centauri places the player in the role of commander of the defense of Earth's first colony on Proxima Centauri. Beta 3 adds a scenario editor where players can create and share their own missions, and a new endless mode that allows users to see how long they can last against a limitless onslaught of enemies.

“It’s always been important for us here at Stardock to put customization into the hands of the players,” said lead designer Derek Paxton. “Beta 3’s scenario workshop does exactly that: it lets people who have always wanted to design their own tower defense games create their own maps and missions.” Players can learn more about how to make their own scenarios with the Modder’s Guide.

Endless mode is a highly anticipated feature that has also made its way into the Beta 3 update. Players can attempt to survive increasingly difficult enemy waves on a few new maps that will present them with some very challenging choices.

Several new towers, enemies, and upgrades that make for deeper strategic choices are also in Beta 3. In addition, new scenarios that continue the story of the colony’s struggles are ready for players to explore.

The Early Access program is designed to allow fans to have input into game mechanics, pacing, and balance. Stardock has been releasing frequent updates based on player feedback.

“Beta updates and community feedback are a critical part of Stardock’s development process,” said Paxton. “We’ve been really happy with how the fans have helped shape this game.”

Siege of Centauri is currently in Early Access on Steam for $9.99. The final version is expected to sell for $14.99. For more information on what’s new in Beta 3, visit the forums.
