Security Guard

Lore & Background

In the RollerCoaster Tycoon world, a park is judged by its guests, and guests judge everything they can see. A crumpled ice-cream wrapper near the entrance, a splash of green on the queue path for the top roller coaster—these small indignities compound. Guests stop smiling, their satisfaction meters dip, and word spreads in that vague, word-of-mouth way the game's reputation system simulates. The Security Guard exists in this ecosystem as the direct countermeasure. They are not a character with a backstory, a name, or a personal arc. They are a function made flesh: a uniformed figure on a loop, eyes scanning the ground for the little green-and-brown blemishes that signal a park has slipped.

What makes them endearing to players is how essential yet invisible they are. A park can survive a day without a new ride, without a fresh entertainment act, even without a handyman fixing a broken station. But leave a vomit splat in the middle of the main promenade for too long, and the guest count will tell you the cost. The Security Guard's patrol pattern is simple—walk, spot, collect, repeat—but the strategic placement of multiple guards across a sprawling park is a small, satisfying puzzle. You learn which corners of your layout get the most traffic, which queue lines generate the most queasy guests, and where a single guard can cover the most ground.

In the broader RCT mythology, the Security Guard occupies the same narrative tier as the Handyman or the Mechanic: a necessary worker in a world where the player is the sole creative and managerial force. They do not speak, do not emote, do not appear in any cutscene. They simply do the job, frame after frame, in that distinctive low-poly, brightly colored park world that has defined the franchise for over two decades.

Reader's Guide

The Security Guard is your first line of defense against the two most common guest complaints in RollerCoaster Tycoon: litter on the ground and vomit in the walkways. Both directly reduce guest happiness and, over time, your overall park rating. Without adequate security coverage, a single missed vomit splat near a popular ride can cascade into a string of unhappy guests who stop spending money and start leaving early.

When hiring, think in zones rather than headcount. A sprawling park with a dense cluster of rides near the entrance needs more guards in that high-traffic core than in the quiet back corner where the wooden coaster sits. Place guards so their patrol paths overlap the main walkways and queue lines, especially near rides with high nausea values. A guard left patrolling an empty field is a guard not cleaning a splat.

Their AI is straightforward: they walk within their assigned area, lock onto the nearest piece of litter or vomit, collect it, and resume their loop. They do not prioritize vomit over litter, and they do not respond to guest complaints directly. If you see a cluster of green splats forming near a particularly sick-inducing coaster, that is your cue to add a dedicated guard to that section rather than relying on a generalist.

Practical tip: in the early game, one or two guards covering the central promenade is usually sufficient. As your park grows and you add more intense rides, scale up. Check the guest comment panel regularly—phrases about litter or messiness are your direct signal that coverage is thin somewhere in the layout.

Did You Know?

• Security Guards are one of only five standard staff categories in the classic RollerCoaster Tycoon games, alongside Rides staff, Entertainment, Handymen, and Mechanics.
• Their entire AI loop is built around proximity: they always target the nearest piece of litter or vomit within their patrol area, with no priority ranking between the two types of mess.
• In the game's visual language, the mess they clean is rendered as small, bright green-and-brown splats and tiny litter sprites, making their work visible and satisfying to watch in real time.
• Unlike Handymen or Mechanics, Security Guards have no interaction with rides, buildings, or guests—they are purely a ground-level cleanup role, which makes their placement strategy simpler but no less critical.
