SiN Episodes Level Creation

In Sin Episodes there is a lot of secret areas scattered around the game for the player to find like in Half-Life 2 with lambda caches, which upon doing so will mostly promote the player by giving them either an item crate, ammunition or some health pack of sort for the work and time put into finding the hidden secret. This is not always the case through by which sometimes the player can instead find either a stationary 'dope' fish or just trigger or mark the event of being able to find another bigger secret located elsewhere in the same level. Most of the time it must be difficult to find the secrets as they are hidden in areas the player might not look after them but can in addition require the player to either stack objects to reach it, being skilled by using maneuvers like jumping or crouching, destroying power generators or must be opened by pushing a series of buttons to unlock; sometimes multiple times. There is a total of 44 actual secrets in the game (easter eggs does not classify) and is individually obtained once the player enters a trigger secret brush that will play a short music sound effect letting the player aware of the achievement, display a hud hint with 'You have found a secret!' and sometimes also on walls a tiki decal will be sprayed or something else entirely depending on the type of secret. The following list contains all of the secret areas in the order they appear in game, with a description about how to access each and every one, bundled together with images of the secrets themselves and what number they are in both the whole game and the given level in general.

Note: Due to a possible oversight in the game, the stats menu panel will say there is only one secret to be found in 'U4 Lab - Infiltration' (se1_u4lab01), except this is not the case and there is actually two.

1 1 This is the first secret in the game and can be found right after talking with Garrison, where a series of grunts will attack and destroy a section of wooden floor boards with explosive barrels. From here jump down into the water below and swim all the way to the end towards where Garrison stands on top, which will reveal a dopefish in the murky waters.

2 2 Jessica has just taught the player about the health mechanics in the game and left by squeezing through an opening in a malfunctioning door. Another door will get blown open from where the player will be on a tight industrial road and then instead of going left, go right instead to the end of a parked trailer. Open its doors and the secret will unlock, giving the player a pair of item crates and ammunition.

10 2 At this point the player will just have finished a sequence involving being inside a shipping container that is simultaneously moved from a thin pipe covered bridge to a railyard, over a large body of water. Jump down onto the tracks or any of the train cars when the container has stopped moving and then walk over to the blue transformer surrounded by a chainlink fence, with the secret being hidden just behind it with two item crates.

14 6 When trying to enter the warehouse the player will have to fight enemies in an enclosed yard.

This will warp the player to the bridges of the roof of the warehouse, on top of all the action, triggering the secret and supplying item crates and some health on the opposite side of the teleport destination.

18 2 This secret is one of the more complex secrets in the game to find and requires a bit of setup to gain access to, but is compared to the rest more a combination of an easter egg and a secret. When entering a mutant autopsy room after going through the attic, go down the stairs to the right into the laboratory with the mutant gas chambers and through the two glass doors in front. Here a bunch of lab equipment will be located on tables and walls down the platform, with the location of the secret itself being behind the door on the floor below with three bright red lights right over it.
