Castle Eggman Zone

Castle Eggman Zone is the fourth Zone of SRB2. The first act is considered one of the weakest levels and is being completely remade for 2.2. The second one, however, will not be remade. It features a diverse variety of gimmicks and enemies to impede your siege.

Overview
Castle Eggman is set in a forest around an old, abandoned castle which Eggman has taken over and turned into a base of operations. The second act takes place within the castle. The whole area is outfitted with defense methods from cannonball launchers to flamethrowers to a big stabby robot.

Acts
A very weak, boring level that is being completely redone for 2.2. It is set in a forest around Eggman's castle with a stormy skybox. It uses wood textures instead of castle ones and has oddly-coloured water. Eggman has outfitted a few traps and a lot of robots to this area to prevent you from entering his castle. It has two Emerald Tokens.

This Act is much longer and more complex than Act 1. This level is set inside the castle. It is outfitted with flamethrowers, spinning maces, chains and bottomless pits. There is a secret Knuckles path and multiple ways to get through the level. It uses the same skybox as Act 1 and a library area at the end. It has three Emerald Tokens.

The fourth Boss level. It involves Eggman in a cage and some swinging maces. Occasionally his cage will lift up, giving you a chance to hit him. After a few hits, he will take his maces with him to the sky in which you must use two chains to get up to and hit him. The pit around his cage is filled with spikes. The level ends via Egg Capsule.

Main things
This level's forest act is very boring and uninteresting. There are barely any secrets. Act 2 is just what you would expect from a big fancy castle belonging to Eggman. This area has a lot of gimmicks seen nowhere else in the game.
