World Fighters Simulator Update 1 Guide, New F2P Raids, Units & QoL

World Fighters Simulator just dropped its first major update, and it brings a mix of new content, quality-of-life changes, and features that actually help free-to-play players progress faster. From a brand-new zone to a fresh raid mode, there’s a lot to go through if you want to stay ahead. Here’s a full breakdown of everything added in Update 1 and how you should approach it.

New Zone: Tempest Federation

The biggest highlight is the new zone called Tempest Federation. What’s new here:

• 6 new enemies
• 6 new units
• New star (banner) to summon from
• New secret unit available

This zone becomes your main progression area after the previous world. The enemies are noticeably stronger, so make sure your team is properly upgraded before farming here.

New Gacha and Units

A new star (banner) has been added in the Tempest Federation.

Key points:

• Includes Mythic units like Rimuru
• Has a secret unit (likely top-tier DPS)
• Designed for late-game progression

Tip:

• Skip lower rarity units and focus on Mythic farming
• Use auto-roll to speed up summons

Tempest Upgrades System

A brand-new upgrade system is introduced in this update. You can now upgrade:

• Attack Distance
• Attack Speed
• Damage
• Power
• Crystal efficiency

This system is especially important for the new raid mode, since range plays a huge role.

New Rename System (Hidden Buff Feature)

One of the most interesting additions is the renaming system.

How it works:

• Rename your unit
• Get a random power multiplier

Example:

• A unit can gain around 1.3x or higher power boost

This is basically a hidden buff mechanic.

Tips:

• Try multiple names to reroll boosts
• Use it on your strongest units only
• Focus on high multipliers for endgame

New Game Mode: Tempest Invasion (F2P Friendly)

This is the biggest gameplay addition. Tempest Invasion is a raid-style mode:

• Requires a Slime Key to enter
• Features up to 100 waves
• Rewards scale with progress

Gameplay basics:

• You stand in the center
• Enemies come from all directions
• Range upgrades become very important

Tempest Invasion is currently:

• The best place to AFK grind
• A major source of new currency
• Required for achievements and progression

Achievements go up to:

• Wave 5, 10, 15… all the way to 100

Even reaching wave 10–15 early is already good progress.

How to Get Slime Keys

To enter the raid, you need Slime Keys. Current ways to get them:

• Drops from enemies
• Secret boss drops
• Possibly from future updates

If you don’t have keys yet, focus on farming the new zone first.

Secret Boss Location (Hidden Spot)

There is a hidden boss in the Tempest Federation that many players miss. How to find it:

• Go near the Tempest Raid area
• Head to the back-left side
• Look for a colored building (yellow/green/red)
• Drop down into the corner
• Enter the hidden tunnel

Rewards include:

• Slime Keys
• Demon Tokens
• Wings and cosmetics
• Crystals

This boss is one of the best farming sources right now.

Primordial Demon Gacha

Another new system is the Primordial Demon gacha. What you get:

• Damage boosts
• Gacha luck boosts
• Rare upgrades

Tip:

• Prioritize “Gacha Luck” bonuses
• Helps you get Mythic and Secret units faster

New Awakenings

Update 1 adds 4 new awakenings. These allow you to:

• Push your unit power even further
• Increase overall scaling

If you’re already near max awakening, this update gives you more room to grow.

Quality of Life (QoL) Changes

This update also improves the overall experience:

• Gems added to chests (huge for F2P)
• New music and sound effects
• Mount dash feature added
• Position saving improvements
• Bug fixes (less crashes and kicks)

These changes make the game smoother and more rewarding to play.

F2P Progression Tips (Important)

If you’re playing without spending Robux, focus on this:

• Farm Tempest Invasion AFK Use auto systems, Upgrade range first
• Target Mythic Units Only Don’t waste time on low rarity
• Use Rename Buff Wisely Only on your main team
• Hunt the Secret Boss Best source of keys and currency
• Upgrade Range Early Helps you clear more waves easily

World Fighters Simulator Update 1 focuses on expanding progression while making the game more rewarding for both active and AFK players. The Tempest Invasion mode alone adds a new layer of grinding, while systems like renaming and upgrades give you more ways to scale your power. If you want to stay ahead, your main focus right now should be farming the new zone, unlocking better units, and pushing as far as possible in the raid mode. With more updates already planned, this is a good time to build a strong account before even harder content arrives.
