PUBG 7.3 Update – How to Use C4

The PUBG 7.3 update has made some major tweaks to the game and added C4. Here's a full rundown of the patch notes.

The PUBG 7.3 update is now live on PC test servers and is introducing a new item to the game, alongside a handful of other tweaks and changes. The biggest feature in the update is the addition of C4, a new throwable explosive item that players can use at their leisure. However, there are also some important tweaks that have been made to the timing of car explosions and a whole lot more. Let’s take a look at the latest PUBG update.

PUBG 7.3 Update – C4, Car Explosions, Parachute Follow

The main talking point in the PUBG 7.3 update is the addition of C4, a new throwable and explosive item. Players can find C4 in the game as world loot and through care packages and can use it simply by throwing it on almost any surface. When it lands, it will begin beeping until it eventually goes boom. It will take 16 seconds to explode and isn’t designed to be used as a stealthy throwable, but to force a camper out of hiding. Due to its long explosion time and easy to hear a beeping noise, you should be able to force a camper out of hiding and pick them off from a distance.

In the video below, you’ll find a complete explanation of how C4 works in PUBG as well as some of the other changes included in the 7.3 update.

One of the other main tweaks in the PUBG 7.3 update is that cars will no longer instantly explode when its health bar reaches zero. Instead, when its health bar is depleted, the engine will catch on fire for five seconds before it explodes, giving players a chance to make a run for it before they meet a fiery death. Vehicles also now have three hit zones, which deal different amounts of damage to their health. Here’s a breakdown:

  • Engine: 100%
  • Body: 75%
  • Roof: 50%

The last major change with the PUBG 7.3 update is the return of the parachute follow feature, which allows teams to easily drop together. This feature was removed in a previous update due to some technical issues but is now making a grand return. Going forward, players can once again select a teammate to follow to ensure that they land together. If you’d like to break off from your teammate after selecting to follow them, you can do that as well.

PUBG 7.3 Patch Notes

Below you’ll find the full PUBG 7.3 update patch notes. 


Season 7 Vehicle Balance

Vehicles are crucial tools on the Battlegrounds, and for a while now there’s been some frustration around dying instantly when your vehicle explodes. This patch seeks to add some more realistic survivability to how vehicles take damage and gives players a small window to bail out before the final explosion takes place.

Explosion Mechanic Changes

  • Vehicles no longer explode instantly upon reaching 0 HP. Instead, engines are now disabled and set on fire, causing the vehicle to explode after 5 seconds
  • Vehicles can still explode instantly if taking large radial damage, like from Red Zones, C4 etc.
  • Exploding vehicles now receive both linear and angular velocity, instead of only linear (vehicle movement after exploding should look a bit less static now)
  • Additionally, vehicles will no longer receive increased collision damage when they’re rolled over

Vehicle Damage Changes

  • Most vehicles now have multiple damage zones which apply different damage multipliers
    • Applies to the following vehicles: Buggy, Dacia, UAZ, Mirado, Pickup, Rony and Zima
      • All other vehicles receive damage as before, equally regardless of area hit
  • Damage zones:
    • Engine – 100% Damage
      • Engine area, usually located at the front
    • Body – 75% Damage
      • Front and rear doors, rear and bottom sides of body
    • Roof – 50% Damage
      • Roof panel, roof pillars, seats, mirrors
  • Boat Armor Upgrade
    • Boats are now granted 5 static damage reduction

New Throwable: C4

C4 is an interesting and powerful new tool that gives players new ways to strategically flush out timid opponents. With a massive 25 meter effective radius and damage that can penetrate cover, you’ll be wanting to run away when you hear this beeping brick of boom. A quick note about C4, we don’t intend this to be just another throwable. It has a pretty short range, but can be used to cut off enemy entry into a building or new zone, or as mentioned above can force enemies out of their safe positions.

  • C4 will start beeping and automatically detonate 16 seconds after being thrown
    • Detonation cannot be stopped or activated early
    • There is a warning LED on the C4 and audible beeping with increasing intensity, clearly audible inside the damage radius which warns you of the upcoming explosion
  • C4 sticks to most surfaces, including vehicles
    • It doesn’t stick to players
  • Effective damage radius is 25 metres, with a lethal damage radius of 15 meters
    • Damage extends vertically, but with slightly less range (lethal radius of 12.5 meters vertically)
    • The shockwave emitted from the explosion is so powerful it damages all enemies within its radius, even if they’re behind cover
  • Due to the weight of the C4 you can’t throw it far and you can’t carry many
  • Found as world loot on Erangel, Miramar, Vikendi and Sanhok

Good luck and try not to blow yourself up!

Spike Trap

Spike traps aren’t quite as effective as we hoped, so we’re increasing their length by 50% to make those trapped choke points more difficult to get around.

  • Spike Trap length increased by 50%

Vikendi Loot Balance

  • Increased DMR spawns slightly

Parachute Follow Feature

Added parachute follow back to normal matches to help teammates land together.
This feature was temporarily removed after its addition in Update 6.2 due to some technical issues which have now been resolved.

  • During the pre-match countdown, follow UI will be shown at the bottom left of the screen.
  • Open the map to select a teammate to follow.
  • You can still select a teammate to follow up until exiting the plane.
  • After selecting a teammate to follow, you can cancel on the map screen, or also by holding F while in the plane, or while actively following a player in your parachute.
  • If you’re obstructed by terrain or an object, your follow will be cancelled.
  • A new icon has been added to better highlight the “Disable Follow” option

  • The current Ranked season will end with maintenance on July 22nd, with a new season commencing immediately after completion of maintenance

Map selection ratio adjustment:

Sanhok Ratio Decreased

  • Decreased frequency in which you’ll get Sanhok in Ranked Mode
    • We have been having discussions internally and looking at player feedback in regards to the Ranked Mode experience of Sanhok. The experience it offers is generally quite different to the larger maps and we have even considered removing it from Ranked Mode entirely. Although, there are of course many players who do enjoy Sanhok in Ranked, so for now we’ve decided to just slightly reduce the frequency in which you’ll get Sanhok matches in ranked.
  • Please keep the feedback coming on this.
