Borderlands 4 drops Vault Hunters into the vast and dangerous world of Kairos, where survival depends on smart choices and quick reflexes. Whether you’re new to the series or a long-time looter, the game throws plenty of mechanics at you right from the start. These quick tips will help you get the most out of your adventure while staying one step ahead of the Timekeeper’s forces.

1. Don’t Forget Your Repkit
Your Repkit is more than just a health item—it’s your lifeline in battle. It restores health instantly, regenerates more over time, and can even reduce incoming damage for a short period. Since it has no downside, use it freely whenever it’s off cooldown. Keeping an eye on its timer in your HUD can often mean the difference between victory and a respawn.
2. Make Full Use of Ordnance
The new Ordnance slot is where the heaviest firepower lives. Rocket launchers, massive energy cannons, and heavy machine guns can all be unleashed without worrying about ammo, since they recharge on cooldown instead. Always activate Ordnance in tough fights—saving it only delays your advantage.
3. Stay Mobile With New Movement Abilities
Borderlands 4 introduces expanded movement options like double jumps, glides, grapples, and dashes. These are especially vital during boss encounters, where staying still is a death sentence. Learn to weave dodges into your shooting rhythm to stay alive while keeping your damage output high.
4. Match Elemental Damage to Enemy Health Bars
Every enemy on Kairos has a weakness tied to their health bar color:
- Red (Bio) – Weak to Incendiary damage.
- Blue (Shield) – Weak to Shock, with Radiation as a solid backup.
- Yellow (Armor) – Weak to Corrosive, with Cryo also effective.
Adapting your loadout to these weaknesses is essential, especially in Ultimate Vault Hunter Mode, where resistances and weaknesses matter much more.
5. Capture Silos for Exploration and Fast Travel
Silos are scattered across Kairos and act as mini-objectives. Reclaiming one grants a fast travel point, unlocks ziplines for aerial navigation, and reveals the location of Vault Key Fragments. Prioritize these whenever possible—they save time and unlock vital progression paths.
6. Collect Vault Key Fragments to Unlock Primordial Vaults
Assembling Vault Keys lets you open Primordial Vaults, challenging endgame dungeons filled with powerful enemies and rare loot. Be ready for intense battles, but know the reward is worth it: Vault clears upgrade your glide pack, giving you longer airtime and more mobility options.
7. Side Missions Pay Off
Side quests aren’t just filler—they grant cosmetics, bonus XP, cash, and sometimes powerful weapons. Many become available as you progress, so keep checking your map regularly. Beyond loot, they’re also a great way to experience Borderlands’ signature humor and world-building.
8. Balance Solo and Co-op Play
Borderlands 4 makes it seamless to switch between solo and co-op. Progress carries over between modes, and drop-in/drop-out multiplayer is smoother than ever. With new features like party-wide cutscenes and difficulty scaling per player, don’t hesitate to jump in with friends or take a break to play solo.
9. Use Fast Travel to Reunite With Your Team
Kairos is the largest Borderlands world yet, and it’s easy to get separated. The new party-based Fast Travel lets you instantly teleport to teammates. Whether you’ve gone exploring or taken a wrong turn, you can regroup quickly without wasting time backtracking.
10. Manage Crossplay and Sessions Settings
In the Session Settings menu, you can control crossplay, party privacy, and difficulty scaling. Want only friends in your party? Set it to Friends Only. Prefer to adjust your own difficulty without affecting others? Enable individualized scaling. These tools make multiplayer flexible for every Vault Hunter.
