IMPORTANT UPDATE! Two GTA 5 mods have been found to contain malware. One, Angry Planes, was featured on this page and has since been removed. Another infected mod was No Clip (not featured here). If we hear of anything else we'll update you. Please visit this gtaforums thread for more information.
We've added a whole new page to our list of the best GTA 5 mods, so you can fill your game with even more destruction, customization, and fun. On the last page, we'll tell you what you need to install your mods. This article was originally published on May 6, 2015, but we're updating it regularly, so come back later for more.
A warning before we start: Rockstar has clarified its stance on modding, and has said it does not ban players for modding their single-player game. Still, it's not clear what the consequences might be if you have single-player mods installed while you're playing online, even if you don't use them, so mod at your own risk. Don't ever use mods in GTA Online, and to play it safe, don't join GTA Online with even single-player mods installed.
Army Spawns at 5 stars
Crime and Police Rebalance mod
Ever stealthily whack someone with a silenced pistol, in the absence of witnesses, and somehow the police still know? This Crime and Police Rebalance mod makes some changes in your favor. More crimes require a living witness to phone the cops, and the mod also slows down increases to your wanted level.
Trucking Missions script
Want a legit way to make a living? The Trucking Missions script gives you six different big-rig driving jobs to complete. Some are time-based, others focus on delivering cargo with as little damage as possible. You even have your own trucking office.
Ped Chaos script
Looks like the citizens of Los Santos have had it with simply being victims of your rampages, and are taking matters—and guns—into their own hands. With the Ped Chaos script, everyone in the city is armed and dangerous, and the cops are nowhere to be found. Watch citizens go to war with each other or join in yourself.
Open All Interiors
During GTA 5's storyline you'll visit the interiors of lots of buildings, such as the LifeInvader offices and the Sandy Shores Sheriffs Department, but you'll find these locations locked up if you ever return. The Open All Interiors script makes over 30 of these locations accessible during freeplay, giving you some great spots for shootouts with the fuzz or for just exploring at your leisure.
No Water/Tsunami/Atlantis mod
Want to play with the ocean level in GTA 5? This water mod has got you covered, literally, by giving you the ability to drown Los Santos in seawater. You can also remove the ocean altogether and drive around on the dry seabed. Using the experimental 'crazy waves' feature may cause game crashes, so make sure you read the instructions on the mod page carefully.
Tap Key for Radio Off
The radio stations in GTA 5 are great, but sometimes you just want to shut the tunes off and concentrate. Instead of having to use the radial menu, which can be tricky if you're in the middle of some high-speed driving, this radio script lets you simply toggle the radio off with a single keypress.
Working Restaurants script
Want to dine at Burgershot or Up-N-Atom? The Working Restaurants script adds the ability to snarf a quick, health-restoring meal at nine different restaurants. Navigate to the new icons on your map, stand under the yellow arrow by the front door, and chow down. Dining only costs a couple bucks, fills your health, and advances the clock by a half-hour.
Simple Passenger script
Feel like doing some hitchhiking? The Simple Passenger script lets you climb into NPC-driven cars, but instead of dumping the driver on the street you can ride as a passenger. Set waypoints for the driver and they'll bring you there, or let them decide where to go. You can also enable drive-by shootings, and if you get tired of being a passenger, you can switch to the driver's seat with a keypress.
A lot of thought has been put into GTA 5's cars, but what about the go-juice that keeps them running? Using the Fuel script means your car will slowly run out of gas as you drive. It also adds a gas tank meter (just above your minimap) to let you know when you're low on petrol, which you can refill by visiting a gas station or using a jerry can.
