Upgrading your weapons in Half-Life: Alyx can mean the difference between surviving a Combine ambush and starting over at your last save. The Half-Life: Alyx Upgrade Calculator helps you track your Resin resources and determine how much more you need to unlock your next weapon mod, health station, or utility upgrade. It’s the perfect companion for planning your progression — without wasting resources.

How to Use The Half-Life: Alyx Upgrade Calculator

1. Select your Upgrade Type: Weapon Mods, Health Stations, or Utilities.

2. Enter how many Resources you currently have.

3. Enter the total Resources required for the upgrade you’re working toward.

4. The calculator instantly shows how much more Resin you need to collect.

No more guessing — just clear, focused planning.

Key Factors That Influence Upgrade Planning

• Upgrade Type:
  Weapon Mods often cost the most Resin but provide powerful benefits like burst fire or laser sights. Health Stations and Utilities usually require less, but can still save your life.

• Resin Resource Management:
  Resin is finite in each level. Being aware of what you can afford means you won’t overspend on minor upgrades while missing out on endgame firepower.

• Progression Timing:
  Some upgrades aren’t available until later in the story. This calculator helps you budget ahead of time so you’re ready when they are.

Example Scenario

Let’s say you want to install a Reflex Sight for your pistol:

• Upgrade Type: Weapon Mods

• Current Resin: 25

• Required Resin: 35

The calculator returns:

• Resin Still Needed: 10

This tells you exactly how much more exploration and scavenging you’ll need to do before heading back to a Combine Fabricator.

Common Mistakes to Avoid

• Upgrading too early: Saving for the more impactful upgrades can be more efficient than grabbing early, low-cost mods.

• Not exploring side paths: Resin is often hidden in hard-to-reach or off-path locations — worth the effort.

• Forgetting about power usage: Some upgrades tie into power or ammo drain — be sure the upgrade is worth the tradeoff.

• Overestimating Resin availability: Resin doesn’t infinitely respawn — manage your upgrades wisely.

This tool helps Half-Life: Alyx players:

• Track how much Resin they still need for key upgrades
