Borderlands 4’s Ordnance Slot Could Be Its Secret Weapon

Borderlands 4 has been doling out more and more about its story, world, and gameplay here lately, with its most recent reveal taking place during a recent State of Play event with PlayStation. During the reveal, Gearbox went over many of Borderlands 4‘s new features — including its traversal mechanics, lower legendary drop rates, Licensed Parts system, new weapon manufacturers, and more. It was a hefty showcase, to say the least, but one of its most significant overhauls, the Ordnance slot, could be Borderlands 4‘s secret weapon.

Near the end of Borderlands 4‘s State of Play event, Gearbox gave fans a brief but satisfying look at its new Ordnance slot, which sees grenades and heavy weapons tied to a cooldown instead of being treated like normal items. At first glance, the Ordnance slot feels like a simple change implemented to make things more accessible for players, but it has a much more far-reaching impact than that. In short, tying grenades and heavy weapons to a cooldown-based skill slot in Borderlands 4 not only fixes a series-long combat problem but also expands what players will be able to accomplish with their character builds.

The Ordnance Slot Means No More Hoarding Heavy Weapons for Boss Fights

Gearbox explained during the State of Play event that the purpose behind implementing the Ordnance slot was to ensure players would no longer have to save their big guns for the game’s most powerful enemies, as the Ordnance slot doesn’t take up a normal weapon slot, nor does it require ammo. Instead, the Ordnance slot uses a cooldown, allowing players to be more strategic with their use of heavy weapons like rocket launchers, as opposed to simply hoarding the weapons and ammo for Borderlands 4‘s boss fights.

According to Gearbox, players will be able to use their heavy weapons and grenades in Borderlands 4 “as often as you want,” though they will still need to pay attention to their Ordnance cooldown. It’s unclear how punishing the cooldown will be, but it’s safe to assume that, while the cooldown may be fairly lengthy from the start, players can likely upgrade their Ordnance slot to decrease the amount of time between uses. Nevertheless, even if players enter a boss fight while their Ordnance slot is on cooldown, they will simply need to wait for the timer to run out to use it again, as opposed to trying to find ammo.

Grenades and Heavy Weapons Could Become Core to Every Build, Not Just a Backup Plan

The fact that players won’t need to hoard ammo or take up a weapon slot with a heavy weapon is a substantial improvement the series has long needed, but that is also going to affect character builds in Borderlands 4. By removing the ammo constraint and the need for a weapon slot, Borderlands 4‘s Ordnance slot lets players experiment more with their loadouts, and they can also feel more comfortable using them in regular combat scenarios, rather than merely during boss fights.

In essence, the Ordnance slot is a well-rounded game-changer for Borderlands 4 that adds to build diversity and makes heavy weapons and grenades more of a regular part of players’ rotations. This is just a testament to how Borderlands has always emphasized personal expression and player agency, but how much more so Borderlands 4 is leaning into that. It will be interesting to see what combinations players come up with, now that heavy weapons and grenades are considered essential parts of combat overall.
