Description
The Hidden is an enemy that cannot be attacked by towers without hidden detection that appears in Easy, Casual, Legacy Molten, Intermediate, Molten, Basic Arena PVP and Molten Arena PVP modes, and the Tutorial. It serves to introduce the need for hidden detection, and can be a nuisance without it. It is slightly faster than the Normal and Abnormal.
The Grave Digger had a chance to spawn the Hidden with its Triumphing Sheol ability in Easy mode. The Hidden was also formerly spawned by the Necromancer before its replacement. The Tombstone could also spawn the Hidden before its removal. The Mystery can summon the Hidden upon death.
It also appeared as parts of the SFOTH Event, Metaverse Champions Event and The Classic Event.
Appearance
The current version of the Hidden is a humanoid with a dark grey translucent body with a slime-like texture. It is faceless, wears a black blindfold and emits black smoke from its body.
The first version of the Hidden had a dark grey translucent body, as well as a dark grey blindfold. It was faceless and emitted grey particles.
The current version of the legacy Hidden has a translucent grey body. It has a black cobblestone torso and legs and wears a black headband on its head. It has a glowing white scar on its face, which has two leaks on the right side of its face.
The current Enemies Beta version of the Hidden has a dark grey translucent body, as well as a dark grey blindfold. It is faceless and emits grey particles.
The third version of the legacy Hidden is similar to the current version, except it has a sad face.
The second version of the legacy Hidden had a light grey skin color, as well as a navy granite torso and dark navy granite legs. It wore a black headband and had a drooling zombie face.
The first version of the legacy Hidden was a white translucent ghost with its torso and legs being slightly less translucent and grey in color. It had a drooling zombie face.
Strategy
- Most early game towers tend to gain hidden detection on one of its upgrades; these towers are sufficient to deal with early Hiddens. Such towers include the Soldier, Sniper, Shotgunner, Militant, Assassin, and Golden Scout.
- As Hiddens spawn in hordes, the Golden Pyromancer is particularly useful, being able to damage multiple enemies at once and having hidden detection by default. The regular Pyromancer also gains hidden detection at Level 2 and is a less effective, but still strong tower against Hiddens.
- If you can use the Farm well, the Minigunner and Accelerator are feasible choices, though they are not necessary and are fairly expensive, especially in Easy mode.
- For splash damage towers that cannot target Hiddens, such as the Mortar and Demoman, if a Hidden is caught up in an explosion, they will be dealt splash damage.
- This means that another detectable enemy must be near the Hidden for a splash damage tower to hit it.
- While the Rocketeer has hidden detection, it should not be used early on due to its high upgrade and placement costs.
