Here's a payload cart, but with one more item. Sending an output will cause it to explode where it is. Use this to either make the defending team's victory a bit more astonishing, or have it run into a train and go boom. Just make sure you are using the correct outputs to make sure it works correctly!
Also if you use this be sure to leave credit for me!
The cart's component names are from the ABS Single Stage Payload Gamemode from the Game type library. (sspl_ *Name* )
The default particle is hightower_explosion. You can change the info_particle_system to any other particle such as cinefx_goldrush.
