Castle Corp, full name Castle Corp - Castleware for All Occasions, is a strategy game released on June 25, 2009[1], three days after the release of Double Edged. The player's goal is to save the Castle Corp company, a group made up of knights that sell medieval-related weapons, from a rival company.

Levels[]

Level 1[]

(A statement from the commander shows at the beginning of each level, and can be skipped):

OK troops here's the lowdown...
Happy Family Shields and Accessories Inc have completely monopolised [sic] the market in decorative flags, shields and drapes. Now that we are in a deep recession we just can't compete with their low low prices anymore and they must be stopped! Ready the workforce - we're to invade their tower factories and take them down!

When first introduced to the game, the player starts out with four player knights. The level has two enemies and no collectible cash. Two enemy knights are seen standing on top of two watchtowers. To hit them, the player has to launch knights towards the enemies. The level layout is a flat path of grass with a starting pad to the far left and two towers extending up.

Level 2[]

Well done lads, after taking that tower out our profits have gone up a whole two points!
But let's not let success go to our heads - we've got a long way to go to win this price-war!

The second level has five enemies and no collectible cash. There are two signs with information for the player:

Sign #1:

Levels can be wider than a single screen. Scroll levels by moving the mouse pointer to the edge of the screen or by using the cursor keys.

Sign #2:

Some of your workforce have been captured to slow the progress of Castle Corp. If you save them, they will be able to work for you again the next level!

Between the two signs is a captured knight, Sir Alan, who the player can rescue by hitting the cage with another knight. Five enemy bats are situated in the air, all of which are relatively close to each other. The level layout is a path starting on the lower left, then heading to the right before moving back to the upper left. There is a starting pad at both ends.

Level 3[]

Don't stray too far from the path on this one...
I want to see you take some decisive action!
Make sure to get their gold lads, and we will be able to spend it in the shop on equipment.

There are thirteen enemies and $900 in this level. A sign in the upper left corner reads:

If you encounter a guard in your path, you will do battle!
Keep an eye on your health levels and be prepared to launch yourself away before you get too low!

The playing field is mostly symmetrical, with six enemy knights on the ground. Seven enemy bats hover in the middle between the two background watchtowers with some bags of gold. There are six enemy knights standing on the path, and Sir Cliff is trapped in the top left corner above the sign. There is a starting pad at both ends of the path.

Level 4[]

Watch out troops...they are targeting us with new initiatives!
With a little bit of forward planning we should be able to stay off their radar!

There are a total of four enemies to defeat and $920 available to be collected. A sign in the bottom center reads:

Remember to collect money and you will be able to buy items from the shop to help you in your missions.
You can also sell any items that you buy back to the shop if you change your mind later.

Sir Richard is trapped in a cage next to the sign, and four pig cannons are situated in a row in the middle of the level with bags of money and silver coins placed between them. There are two paths, an upper and a lower, each with a starting pad at either end.

Level 5[]

We may need a little blue-sky thinking on this one...
There's some clever tactics at play so we've got to think outside the box if we are to please the shareholders.

Pipes are introduced to the game, which knights can ricochet off. There are six enemies in the level and $740. A single starting pad is on the left, which leads into an enclosure created by the pipes. A sign is in the enclosure which reads:

You can ricochet off these pipes so use them to gain a tactical advantage!
Try using them to take more damage off the opposition and to collect extra gold so you can buy more items from the shop!

Also in the enclosure is an enemy knight on the path, and two enemy bats hovering beneath it. There are also two enemy knights are above the starting pad on the wall, with an enemy bat just below. To the enemy knights' right are two sets of pipes, with Sir Bob captured at the upper right of the level.

Level 6[]

Their trajectories are on target...
Maybe this is the one time you won't want to get your five-a-day!

There are six enemies and $590 in this level. The path begins with a starting pad on the left, and has three enemy knights on the ground with a row of silver coins. Above them on three separate towers are three vegetable launchers. Above the first two from the left of the screen are pipes, with moneybags and a chest between them. Sir Elton is trapped behind the second pipe section in the top right. Three pipe sections are poking out of the bubbling liquid at the bottom of the level.

All eyes are on us on this one so we had better fight fire with fire!

Don't be afraid to get your fingers burned.

This level has eight enemy bats, two fire eyes, and one enemy knight.

Two remote control steeds and one free-range chickens are necessary to use to complete the level. You may want to bring along three of each.

The fire eye on the left requires using the remote control steeds to run past the fireballs. Once the knight reaches the left platform, charge at the eye to damage it - it requires two hits.

The fire eye on the right requires using the free-range chicken after breaking down the wall. It can be destroyed with a well-placed aim of the free-range chicken, but you may need to use a second in case your aim was slightly off.

Materials[]

  • Ground - The ground is a material found in every level. It is a dirt path with grass growing on the edges. There is a pad on one side of the path and your knights can start to walk to the other side from there. When they come to the end of the path, the jump off and parachute off the screen. Ground can also be used to hold up treasure chests.
  • Stone - Stone is a grey material that can be in the background, but it is also seen holding up ground. Stone is not interactive.
  • Metal pipes - Metal pipes look like wood, but they do not break. If a rocketing Knight touches it, they will bounce off in another direction, instead of going into the pipe. Enemies will sometimes be on positioned on it, but knights cannot walk on it, so the player will have to rocket towards there to knock out the enemy.
  • Breakable wood - Breakable wood is wood that can be broken by a rocketing Knight. When a knight rockets towards it, it will bounce off in the other direction, but not before breaking it first. Breakable wood is mostly used to block enemies, or a trapped knight, making the player use more of their knights to get there.
