The Cerebral Gateway is the final level of Serious Sam: Tormental, accessible only after collecting 32 Mental Keys.
Plot[]
Sam has finally unlocked the gateway that the fragment of Mental was guarding. With time running out for planet Earth, seeing as its own natural satellite is about to collide with it, Sam needs to buy his real self time in the physical realm. All he needs is more time. In order for his physical self to figure out a way to save humanity, the version of Sam dwelling within his arch nemesis's mind needs to find a way of exploiting his weakspot, the source of all of Mental's horrific plans and ideas: the Mental Thought.
Trivia[]
- If the player beats the Fortress level in any point in the game and enters the Cerebral Gateway it will always count as a loop. Homever it won't be counted as a loop if you start from Frontal Lobe and enter the Vault right away.
- After beating the Mental Thought, you will be able to do the "Speedrun+" and "Conqueror" quest which can be found in the form of Scrolls.
- The blue chest in the starting area will always contain the Ultra Serious Cannon, which cannot be obtained at any other point in the game.
