"Castlestorm is no doubt filled to overflowing with features, variety, and fun. The campaign in lengthy, but not to the point of being overly repetitive."

"CastleStorm draws from a seemingly unmanageable array of inspirations including real-time strategy, tower defense, and Angry Birds, and does so with remarkable virtuosity and humor." 8/10

"CastleStorm doesn't try to hide its inspirations, and it doesn't need to. There are enough of them to morph this action strategy into something fresh and exciting. It's warm, frequently funny, and stylish It's just hard enough to keep you biting. And most of all, it's just bloody great." 9/10

“In what is easily one of the greatest moments of my gaming career, I once used my ballista to shoot a dragon out of the sky. The massive lizard corpse fell to the ground, killing three of my opponent’s soldiers. Thank you for making that moment possible, Zen Studios." 83/100

About This Game

Welcome to the world of CastleStorm, a super genre mashup of 2D physics destruction mashed with tower defense brawler! CastleStorm was born out of the fond childhood memory of building and destroying LEGO castles.

The clouds bring rumors of war…It’s Knights vs. Vikings in CastleStorm, where medieval warfare meets 2D physics-based destruction! Controlling the battle in real time, players will harness the power of medieval artillery, manage a fearsome ground attack, and cast powerful spells! CastleStorm features a story-driven solo campaign, a custom castle editor, online multiplayer, co-op modes, and more. Building castles and knocking them down has never been so much fun!

CastleStorm is a physics based tower destruction game, combining elements of real time strategy, resource management, and a beautiful blend of challenging gameplay scenarios.

Multiplayer battles and Co-Op. CastleStorm features multiple modes of multiplayer action for both local and online play:

• 1 vs. 1 split-screen mode, simply try and beat your opponent
• Survival Co-op: Two players team up to fight off waves of enemies together! One player will control the ballista, the other controls ground forces
• Last Stand Co-op: Both players control a hero and fight off endless waves of enemies together!

Build your own castle! CastleStorm features a tower construction editor allowing players to construct their own custom castles that will be used in battle. Castles must be constructed wisely, as choices determine which types of troops and resources will be available during battle!

Twelve incredibly beautiful environments and a comical story. Sir Gareth leads his troops into battle against the raging Vikings to recover the stolen gem and bring peace to the realm!

Multiple paths to victory. You can choose how to defeat your enemy. Capture the flag, destroy their castle, or complete another predetermined level objective in order to claim victory. Each level features multiple objectives, each with their own rewards!

An arsenal that would make any medieval warrior proud! Harness the power of medieval ballista weaponry, and launch an assortment of explosive weapons including Morningstars, Apple Grenades, Homing Eagles, and even flying sheep to defeat an onslaught of enemies trying to capture your flag and destroy your castle. Deploy a fearsome ground attack of swordsmen, knights, and donkey riders in order to protect your castle gates, and if all else fails, call upon powerful spells to help keep the enemy at bay.

You’ve won the battle, now power up so you can win the war! As you power up in CastleStorm, new weapons and troop classes become available for use in battle.

This game deserves a 9.5/10 in my opinion

TLDR; This game took me by surprise, it was so addictive that I spent 2 days straight completing the campaign. This game is a combination of many other games such as angry birds, army of darkness, Age of War and tower defense games. I would highly recommend this game if you have a couple of days to spare and have nothing to do.


  • The campaign was satisfyingly long and does not feel draggy at all since most of the mission has a different and unique objective. Coupled with the DLCs, this game will give you a solid entertainment for a couple of days.
  • The storyline was very interesting and the characters are all very lovable. The substantial amount of humour in the dialogue was very entertaining.
  • Besides shooting catapults trying to destroy the enemy's castle, you can spawn heroes which you can control on the battlefield. You can also spawn a variety of soldiers to aid you in the battle.
  • Multiplayer support so you can play with your friends after you have beaten the campaign. However, there are not many online players at the moment. So you have to get a friend to play it with you.


  • When I was playing this game, I heard a very familiar music on the background. As I went to research, in turns out that the music was composed by the same artist that created the music for the flash game Age of War. The music was indeed a remastered version of the Age of War theme music. I used to play that game alot during high school and I delighted to hear that music again in this game.
  • The other music was very fitting to the game and its quirky characters. Although it does get repetitive sometimes, but it is not really a problem.

CastleStorm took be by surprise. If you ever played Swords & Soldiers, Angry Birds and any other tower defense game - and enjoyed them - CastleStorm is the game for you.

What it basically comes down to, if you haven't played any of those games, is this:
You're the good guy, you own the castle on the left (or right, depending on the mission). Your opponent owns the other, opposite, castle. You both own a ballista that can shoot about 9 or so different ammo types.

The goal is usually to destroy the other castle. This can be done by shooting projectiles at it. Damage it enough and the physics will take over, destroying rooms in the process. These rooms are filled with troops, by the way. Destroy a room with a specific troop and your enemy can't summon those anymore.

Troops can be send to help destroy the castle gate, after which they can then steal the flag. Capturing and returning a flag also results in victory. You can also send your troops to just distract your enemy.

You also own a hero that can be spawned on the battlefield to slay the troops of your enemy. You can summon them for about 20 seconds; after that they disappear and you have to wait a certain amount of time before you can summon them again.

Missions have secondary objectives, keeping the missions fun and varied, while also giving them replayability.

Of course, a tower defense game isn't a tower defense game without upgrades. Thankfully, there are plenty of things to upgrade; projectiles, troops, heroes, spells, your castle, you name it.

The sounds are funny and the textures are beautifully sharp and detailed. It's a gorgeous looking game, in its own way, of course. You can't compare it to, let's say, Crysis (obviously). That would just be silly... ...

Like I said CastleStorm took me by surprise. It's been a long time since I had so much mindless fun with a game ♥

Kind of like Swords & Soldiers (or other 2D lane pushers) but actually good. Pump out troops, cast spells, load the ballista with weird ammo and assume direct control of heroes to wipe the battlefield. The best bit is the artillery, lob stones to smash enemy spires to loose parts which then will hopefully crush the enemy army as they are leaving their castle. There are four factions (with DLC) with different troops/spells/artillery. You can either try to storm the enemy castle with troops, stealing their flag and bringing it home in a tug of war, or you can just simply smash the enemy castle with boulders until there's nothing left. It's just fun and the physics are meaty enough, who wouldn't enjoy breaking things? Lots of opportunity for amazing skillshots or stupid accidents when your ballista hits your own troops. You can also design your own castle, the room choices affect your troop loadout and bonuses.

The four singleplayer campaigns were good enough, but when you enter multiplayer the game commits suicide. Local splitscreen can only be done in tiny windows, leaving lots of the screen unused and black. It was probably to preserve the FOV ratio but the end result is completely unappealing. Online multiplayer then is tied to playing ranked matchmaking, if you want to customize and upgrade your loadout playing with just friends doesn't earn you anything. I don't know why they went this way, did they expect to turn this into e-sports? Multiplayer seems quite dead even during sales...

All in all a very enjoyable time, for some reason I'd compare it with Orcs Must Die even though it's a different type of defense game. The art, humour and design is somehow similar and very polished. There's a nice pile of content and game modes in the complete pack for singleplayer, however if you're interested only in multiplayer I'd say skip it and get something like King Arthur's Gold instead.

This game is super-addictive! If you like games like the Worms series, or Swords & Soldiers or any kind of tower defense games, take a look at this masterpiece!

Even my wife loves it and she's losing her feeling for time on a regular basis with this game.

Singleplayer has four campaigns and it's not just "destroy the enemy castle". There is surprisingly a high variety of different mission types.

Give it a try, it's worth your time and money!

Thumbs SIDEWAYS... the single player campaign is a fun mashup between a tug-of-war, tower defense, and scroller rpg. You play to ear credits to level up skills and can even build your own castle. Eventually you get all stars on all maps, and all skills, and you are still left with an onsluaght-style game which is chaotic and challenging. Single player? Thumbs Up!

Multiplayer however, is a seriously broken, unfun joke. You are given 20k credits. Once you spend them, they are gone - you cannot gain new skills, you cannot reset your 20k to buy different items... EVER. Playing against friends? You gain no credits, so theres no reason to play with them.

The only way to get new credits is to play "ranked" matches which pit you randomly against other players (level 1 vs level 100 anyone?)- and in ranked matches you cannot even choose your opponents, so forget about ever playing with friends.

Multiplayer is horribly designed and very broken, slow and utterly fail, and unless you get this game at a steep discount, or dont mind playing by yourself, I'd say "avoid"
