This is a sub-page of Proto:Counter-Strike: Global Offensive.
Player ModelsThose guys that also got changed. And some guys that didn't make it.General Differences#
Maps#
Only one map is playable in this build: de_dust. It does have its differences though: one being that the way bombsite decals are marked is with a props_gameplay sign and a Counter-Strike: Source arrow decal.
Title Screen#
The title screen was changed before the final release, which was changed two times post-launch. The prototype's title screen seems to randomize between two backgrounds: a blue background with a Counter-Terrorist in the foreground and one with yellow background and a Terrorist in the foreground.

Bot Profile Pictures#
The profile pictures for the bots use the ones from Counter-Strike: Source.
Broken Training Mode#
There is a menu option for training, but it doesn't work in this prototype, as the map file (training1) doesn't exist. Clicking on the Training option will simply reset the menu music.
Broken Splitscreen With Bots#
There is also a menu option for playing split-screen mode, but it doesn't work, even if you have both a keyboard and controller plugged in.
Scavenger Mode#
A game mode removed from the final release of the game. Strings related to it are still in the final game. This gamemode plays similarly to the fan-made Fight Yard mode.
Misc.#
- The executable file uses Portal 2's icon and is called "cstrike15.exe".
- Windows, for some reason, reads the game as "Counter-Strike Source".
"How To Play" Screenshots#
This prototype has very different screenshots used for the "How to Play" section of the options menu. These screenshots seem to be taken from the time Global Offensive was a Counter-Strike: Source console port.





Unused Video#
A credits video that was supposed to be played in the menu.
Sounds#
Title Screen Theme#
The startup theme in the prototype is a completely unique theme. According to the sound file's metadata, its real filename is "cs_menu_01-06".

Instructor#
While the training mode doesn't exist in the prototype, the voicelines for the training instructor are placeholders voiced by Chet Faliszek.
Weapons#
The "slack space" of this build's .vpk files contains some "deleted" files, these early weapon firing sounds being some of them.

Upsell Dialog#
A pop-up screen meant to promote the game, probably used for when the time on the console versions' trial mode ran out. It shows the new features available with purchase and the achievements unlocked after purchasing the game. The command for accessing this screen is gamemenucommand openupselldialog.
Oddities#
player\cs_testing#
Within models\player is an odd subfolder called "cs_testing". This subfolder has no models and only has three .vtx files named "combatpants", "sealteam_dynamic" and "sealteam_greg_dynamic". It is unknown what this folder's purpose was.
