Explodes on impact causing considerable delays to opponent journey times.
— Description, Sonic Forces: Speed Battle
The Explosive Mine is a Trap Item that appears in Sonic Forces: Speed Battle. When used, it will place spiked ball chunks that can block the opponents' way.
The Explosive Mines take the form of black spiked balls.
In gameplay, the Explosive Mine can only be obtained at random from Item Boxes by Omega, Knuckles, Metal Sonic, and Zavok. In addition, Metal Sonic can also obtain it if he uses the Steal Item to steal it from the other users.
When used, three spiked balls will be dropped some distance ahead of the user's current location on all the lanes that the user is not currently on. Touching an Explosive Mine with a playable character (including the user) will cause them to explode instantly, causing the character to lose Rings and drastically slow down. The Explosive Mine can be upgraded for each individual user by upgrading them to levels 4, 10 and 16, increasing the duration a hit opponent is slowed for.
To avoid Explosive Mines, the player must either jump over them, or run in between them.
