How to get the Party Bus Achievement in Halo Infinite

Hop in!

The Party Bus achievement in Halo Infinite has some of the more obscure requirements to complete it. Players must earn a "Mount Up" in a multiplayer match to get the Party Bus achievement. To get a Mount Up and the Party Bus achievement, players must drive a Razorbackhonk the horn, and have three other players enter the vehicle afterward.

Razorbacks are the vehicles that resemble Warthogs but with no turret on the back. Razorbacks also have three passenger seats and a back compartment that can store weapons, items, or objectives.

To honk the horn: Press RT on Xbox, Left click on PC.

Waiting for three other players to get in the vehicle is difficult. If you have three party members, getting the achievement for everybody is easy, but if you are running solo, the best bet is to hope teammates get in. You can also hop into game chat to ask players to help you with the achievement.

Once the Razorback is full of passengers after honking, you should be awarded the Party Bus achievement.
