When you start the game, on the first roof you come to, above a sign saying "Arctic Toys" you will find five objects, which are, from left to right, an apple, an Earth globe, a cake, a hammer and a tap. The first letters of each of these added together (AECHT) is an anagram of the word CHEAT. Pick up the objects in the correct order (Cake, Hammer, Earth globe, Apple and Tap) to receive an invincibility shield lasting 10 minutes. When the cheat is activated, flashing fish form around Robocod, and the music speeds up. Also, if now you go straight into the first room, and then exit immediately you will find that all of the castle doors have been unlocked, allowing you to access any level.
On the sports equipment level after the second spike are five objects in a row, which, in order, are some Lips, a Violin, an Earth globe, an Ice-cream and a Snowman. The first letter of each of these added together spells out LVEIS, which is an anagram of the word LIVES. Collect these in the correct order (Lips, Ice cream, Violin, Earth and Snowman) for infinite lives.
In some point of the game (I do not know where), there are five objects that spell out the word POWER. Collect them in the following order: Penguin, Oil, Wine, Earth and Racquet.

There are two hidden worlds behind the main tower, another sweets level (including a Liquorice Allsorts World, the infamous Bouncing Jelly World, another Cake World and an upside down Jelly World) and an extra scrolling section. To reach them, run along the ground floor - avoiding the doors - then go up and over the first flight of stairs. From the bottom of the second (smaller) tower, make your way up to the landing above Dr. Maybe's final door and run left into the wall. You'll disappear behind the screen and arrive in the Secret Tower room. But who is Katie?
Once you've finished the bath level, drop down to the bottom of the castle, and walk left until you get to the small snowman statues. Jump on these and they'll turn into a moving platform. Once you get to the top of the screen, walk left into thin air and jump. By now you should be next to some doors. Go through them for bonus city!!
Go to the same place after finishing the circus room (the last room before the end of game baddy) and stand on the golden snowmen again. A platform made of two bonud blocks should float upwards, revealing a secret tunnel. At the end of this are even more extra lives and stars.
Do as above after the sweets level, but go to the left of the castle. Go on the snowmen once more, and at the top of the screen grab the umbrella and collect all the goodies while you're floating down.
On the second teddy bear level, keep jumping over the spikes until you see a hole above you. Jump through this and catapult yourself off the bus there. Once you've done this, get on the higher level and keep walking left, bounce on the trampoline and collect the wings. Now fly along the top of the screen to the right and you should find a different exit. Go through this for a special bonus level.
Complete a level with does not feature a guardian and you will always find something new when you return to the castle "selection" screen. In one case you will find a whole sequence of lifts and things (see above) that lead to a door that you cannot normally get to. If you go to the very right of the factory screen and look down you will see a load of crowns, which you can access after coming back from other levels.
It is possible to finish Robocod by only doing half the levels. A choice of two new doors to enter is given when the correct level is completed. Start by completing the Fluffy Toys one and then by doing the Cars one.
Finish the bath levels and as soon as you come out of the door run straight to the golden snowmen in the bottom far left outside the castle. Jump into these snowmen and you'll float upwards to the top of the screen where you'll be met by a door. Getting through this door is tricky but worth it. Inside are loads of extra lives and energy stars. Go to the same place after finishing the circus room (the last room before the end of game baddy) and stand on the golden snowmen again. A platform made of two bonus blocks ahould float upwards revealing a secret tunnel. At the end of this are even more extra lives and stars.
