The studio was originally founded as Lost Boys Games in 2000 by Hermen Hulst and Arjan Brussee, before being re-established as Guerrilla in 2003.

1st Logo (March 28-October 18, 2002)
Logo: On a black background, we see a, roadsign-like diamond with a white drawing of a cactus inside and a piece of the ground below it. The diamond has a black border with white outline. Below is a black rounded rectangle with the white text "FORMULA" inside.

Variants:
 * On Rhino Rumble, the logo is on a white background, with "LOST BOYS GAMES" below the "FORMULA" text.
 * On Invader, the logo flips in, and flickers around as if it was on old, deteriorated film, complete with film scratches.
 * On Black Belt Challenge, the text "Licensed by Nintendo" is seen below in a medieval-esque font.

FX/SFX: None, aside from the animation on Invader.

Music/Sounds: None.

Availability: Uncommon. Seen on Rhino Rumble for Game Boy Color, as well as Invader and Black Belt Challenge on Game Boy Advance.

Editor's Note: None.

1st Logo (September 3-November 2, 2004)
Logo: We see a cubic, stylized "G" symbol, beside the name "GUERRILLA" in modified Authority Regular. "DEVELOPED BY" is seen above, with the byline "GUERRILLA IS A MEDIA REPUBLIC COMPANY" below it all.

Variants:
 * On ShellShock: Nam '67, the logo is.
 * On Killzone, the logo is with white lines of light scanning over it.

FX/SFX: None, aside from the animation on Killzone.

Music/Sounds: On ShellShock: Nam '67, a menacing wind sting. On Killzone, none.

Availability: Uncommon. Seen on ShellShock: Nam '67 for PlayStation 2, Xbox and Windows, and Killzone for PlayStation 2.

Editor's Note: None.

2nd Logo (October 31, 2006-)
Logo: Same as the previous logo, except this time including only the "G" symbol.

Variants:
 * Killzone: Liberation: "Developed by Guerrilla" is seen below the symbol.
 * Killzone 2: We move through a spinning matrix of futuristic, - bars which stop in the middle of the screen to form the G in dark gray, which then is covered by splatters of paint. The logo dissipates back into pieces while zooming toward us.
 * Killzone 3: The Sony Computer Entertainment notice flickers to a CRT and becomes a range of indecipherable symbols (assumedly the language of the Helghast, the rival empire from the Killzone series). Several bars of text are seen passing by before a log-in screen pops up, with the logo of the Helghan empire notably visible at the top. A password is entered, and the animation from the Killzone 2 variant plays (this time tinted, and with several visual glitches).
 * Horizon: Zero Dawn: The text "GUERRILLA" is seen below the G, in addition to a trademark symbol (™) next to it.

FX/SFX: None, or CGI.

Music/Sounds: None or the opening theme of the game. Music/Sounds Variants:
 * Killzone 2: A soft choir, alongside dialogue by the Helghast leader Emperor Visari, continuing into the game's intro cutscene ("My people, sons and daughters of Helghan, this much I vow...")
 * Killzone 3: A somber, depressing orchestral score.

Availability: Common. Seen on Guerrilla games since Killzone: Liberation on PlayStation Portable.

Editor's Note: None.
