Top 5 Ways to Troll Your Friends in REPO

Toilet Trouble

This is a classic way to troll your friends in REPO and thankfully won't harm them in the process. In every REPO map are toilets; some of them have diamonds nestled in the porcelain, but generally they are empty and not worth bothering with, unless you want to have a bit of fun with a team mate.
Each of the toilets has a workable flush which, when used, will make a lot of noise and spray brown toilet water all over the place. Get your fellow bot to jump inside and crouch, if they are suspicious just tell them you want to take a funny screenshot. Once they are inside, flush the toilet and watch as they swirl around in the mucky water and shoot out across the room, covered in poop water.
Abandon Ship!

If you have a team mate who is always to last one back to the truck, this might help speed them up. When every extraction point is complete and you all race back to the truck, avoiding monsters and creatures along the way, you can activate the truck. Any team mates still dawdling around the map will have a quick countdown until they are unceremoniously destroyed and will have to join the team when you get to the shop.
In-Store Fights

The shop doesn't only offer ways to buy upgrades and items, but it is also a great way to test out some of those items and have some fun while doing it. Set mines as traps in doorways, in the truck, and around the shop as boobytraps for your friends, or throw grenades in their direction to see how much damage they can do. Just remember that if any of you lose any health in the shop, you'll not get it back unless you buy a health pack! There is a mod to stop any damage occurring in the shop, if you want the freedom to test every weapon there with no risk of injury.
Secret Modding

A sneaky way to trick and troll your REPO friends is to host a game yourself with one particular mod they will never expect. Wesley's Enemies includes a mimic creature that looks just like a team mate but eventually transforms into a deformed monster with a machine gun. Before shape-shifting, these creatures are shaped just like a normal bot; they will follow you around, look at their map and seem pretty normal, except for the distinct lack of communication.
After a while, or once they are injured, they change into a huge, aggressive monster that shoots anyone who comes near with a huge gun. They are slow-moving, like the Trudge, and too heavy to pick up with out strength upgrades. Adding them to the game without anyone's knowledge is the ultimate troll and guaranteed to freak a few friends out.
Spewer Sidekick

Spewer, or as we like to call him - Slimer, is a small and kinda cute creature who will spew green slime and jump on your face for a period of time. He doesn't do you any harm while on your face but he continues to spew, damaging items and team mates wherever you look. If you want to use him to scare your crew, just chase them down when Spewer is on your face, knocking them over and dealing a bit of damage just for fun. Of course, if you end up killing your own semibot friend, you might have to expect some kind of payback later on.
