An easy way to get the trophy is by creating a private match, setting the team size to 4v4, changing the bot difficulty to No Bots, switching "Joinable By" to "Name/Password" (if you want to do it with one controller), and then give the match a name. Now change the Mutator settings to Max Score: 1 Goal. Once you win the match, the trophy is yours. Spectacular
With Grog, Score 10 Goals against Pro-level Bots or higher 73.99%
Common DLC RequiredCo‑Op or Solo
Ensure that you have the Grog selected as your vehicle. Any accessories will be fine. If you're playing by yourself, set up a 1v1 Exhibition against a Pro-level bot. Use the new Mutators menu to set the time limit for the match to unlimited, so you won't be interrupted. From here, just score 10 goals and the trophy will pop.

If you're playing with a friend (or friends), set up a 2v2 (or 3v3, 4v4 as appropriate) private online match against Pro-level bots. Use the new Mutators menu to set the time limit for the match to unlimited, so you won't be interrupted. Make sure you both select the same team. This might be a little easier because you can set each other up for goals by centering the ball. Once each of you have scored 10 goals, you can quit out. Savage
With Ripper, Score 10 Goals against Pro-level Bots or higher 74.53%

Ensure that you have the Ripper selected as your vehicle. Any accessories will be fine. If you're playing by yourself, set up a 1v1 Exhibition against a Pro-level bot. Use the new Mutators menu to set the time limit for the match to unlimited, so you won't be interrupted. From here, just score 10 goals and the trophy will pop.

Make 50 total "Shots on Goal" using Grog or Ripper 86.56%
Common DLC RequiredCo‑Op or Solo
This will probably be the last trophy in this pack that you'll get. If you play this game quite a bit, you will get this trophy naturally as long as you stick to one of the new vehicles. If you prefer to just get it out of the way, the fastest way to do it is by yourself. Set up a 1v1 Exhibition, but elect not to have any bots. Use the Mutator settings to set the time limit to unlimited. From here, just keep scoring on the empty net until the trophy pops. Again, make sure you're using one of the new cars. Any of the shots you made while working towards other trophies in this pack will have already counted for you, so it's likely you won't need that many more. Psycho-Master Exploder
Equip the Mohawk and Demolish 3 opposing Bots in the Wasteland 78.75%
Common DLC RequiredCo‑Op or Solo
For this trophy, equip the Mohawk topper item on any car. You can either do this solo or with friends on your team, as long as you are playing against bots. When you set up the match, ensure that the new map Wasteland is selected. Set the difficulty to Rookie, as enemies will be less likely to move out of your way when you're charging at them. Once you're in a match, load up on nitro and hold  to build up some momentum. Once your rocket trail turns into a streak, you have enough speed to demolish another vehicle. Destroy 3 bots in this manner and the trophy will pop.

Alternatively, you can use the new Mutator settings to set demolition to "on contact" and you won't have to use turbo at all.
