Insert game

An insert game, or insert war, is the general term for a type of game in which players inserted user-made models in order to fight each other. Insert games usually consisted of an insert tool within the player's inventory and a simple baseplate on which to battle on. Games of this genre were generally criticized for the ease of abuse and spam within the game that one could do.

Due to security updates and other changes that have broken the insert tool from functioning, insert games have seen a very steep decline in popularity and are now very uncommon.

Abuse
Before the InsertService update released, insert games were commonly abused. Players had the ability to insert game-breaking models, such as a forever exploding bomb and admin scripts (which players could then use to loopkill players, kick/ban players, or even prevent new players from entering). Also, they could insert nukes to delete everything within the game. Prior to the InsertService update, certain models called "takeovers" manipulated the game to only allow the model owner to control the game, preventing others from using the main tool.

InsertService Update
An update to the InsertService service has ultimately destroyed insert games as InsertService now only permits the insertion of official Roblox assets (such as hats) and models that the creator of the game owns. The pros and cons of this update varies: insert games are less likely to be abused, but are limited to using primarily gear as a result. Now, only bricks, clothes and hats can be inserted.
