Madness: Project Nexus/Story Mode

Nexusmap1 — The Story Mode Stage selection screen of Episode 1.

The Story Mode gameplay consists of two Episodes with multiple stages that are unlocked as the previous stages are completed. Within each stage, up to four characters can be playable (One player, 3 AI). Before starting the stage, the player can choose which character to play as, and which characters to set as the AI.

Each stage consists of different rooms, each room must be cleared of enemies before proceeding to the next. Each stage has a specific goal or objective, which must be completed in order to finish the stage.

Weapons dropped by enemies may be picked up if you are not holding a weapon. You may hold up to two weapons at once. Special weapons, such as Sanford's hook cannot be discarded. Sanford's hook, which is a melee weapon, also acts as a ranged weapon when the throw button (E) is pressed. It then returns to Sanford.

Along with a health bar, you also have a TAC-BAR. The TAC-BAR consists of four bars, and recharges over time. When you are hit, the TAC-BAR loses a bar. As long as the bar does not empty, your health with not degrade. A.T.P. engineers and A.T.P. soldats also have TAC-BARs of their own how many bars they have is depending on what difficulty you set it to.

Each time an enemy is killed, the bullet-time meter increases.

Episode 1.5 screen selection. — Story Mode, Episode 1.5 screen selection

After at least one kill, the player may press Shift to enter bullet-time, where all movements are reduced to slow motion. However, certain perks in Arena Combat Mode keeps the player's movement speed intact and having low health will end bullet-time prematurely.

In the Episode 1.5, when you reach half-way all the 5th stage (Vaults), the player will get a halo and the bullet-time switches to Magic Bar. When the player presses Shift, Dr. Christoff will pull out some dark beam for his hands or eyes, which will hit the ground, knocking over all the enemies near him. When the player holds Shift, he will throw the beam in front of him and whoever touches the beam will disintegrate upon impact (unless it is a enemy with many lives, or zombies).

Interactive items, such as lockers or doors, can be opened with the spacebar to reveal extra weaponry, or to prime explosives on objects to destroy them.
