The Season 3 Battlepass in Universal Tower Defense X launched with Update 3.0 Part 2 (Universal Festival, Part 2) on June 2, 2026. It introduces two exclusive units, Nursefather at Tier 25 and Big Brother at Tier 50, locked behind 50 tiers of progression. This is the third battlepass in UTDX history, and both units are stronger than their predecessors. Missing them means waiting for a future re-run that isn’t guaranteed. Here’s every reward, how to level fast, and whether the Premium Pass is worth buying.

Based on Valencina from Limbus Company, Nursefather is an Exclusive rarity boss shredder. It deals bonus damage to Hyper Armored enemies, spawns mini-towers, and increases its Critical Damage and Counter Attack chance over time. Compared to the Season 2 Tier 25 unit Ja’frey, Nursefather hits significantly harder in boss-focused content.
Evolution: Nursefather → Nursefather (Thumb) To evolve, visit the Evolutions NPC and submit Frozen, Phantom, and Burning Fragments (available from Virtual Shop, Merchant Shop, or Challenges) plus the Nursefather Fedora, which is also a Season 3 Battlepass reward. No raid grinding needed for the evo — the pass supplies everything.
Big Brother (Ricardo) is the second Exclusive unit, obtainable at Tier 50 of the free track. Its evolved form, Big Brother (Vengeance), is what most players ultimately want.
Evolution: Big Brother → Big Brother (Vengeance) Requires evolution materials obtainable in-game. Check the Evolutions NPC for the exact item list.
Purchasing the Premium Pass unlocks the Shiny variant of Big Brother at Tier 50, alongside doubled currency and resource rewards throughout the track.

The Premium Pass doubles nearly every currency reward and adds Shiny Big Brother. At 799 Robux, it’s worth it if you plan to reroll traits heavily or farm banners — the Universal Gems alone cover multiple summon attempts.

Battlepass EXP comes from completing levels in any game mode and finishing quests. Here’s how to maximize progress:
Pro Tip: Nursefather is the stronger of the two units and its evolution only requires Battlepass rewards — no extra farming. Prioritize reaching Tier 25 before spending time on anything else.
Yes, if you’re an active player. The doubled currencies (Gems, Rerolls, Universal Gems) make trait grinding significantly cheaper over the season’s duration. Shiny Big Brother is cosmetically distinct but not a separate competitive unit. The 799 Robux price is in line with previous seasons.
Skip it if you’re a casual player who mainly wants the units — both Nursefather and Big Brother are free at Tier 25 and Tier 50 respectively.
Nursefather (Tier 25) and Big Brother (Tier 50) are the two Season 3 exclusives. Both are Exclusive rarity. The Premium track also unlocks Shiny Big Brother at Tier 50.
Reach Tier 25 on the Season 3 free reward track. Progress by clearing any game mode stages and completing quests to earn Battlepass EXP.
The Premium Pass costs 799 Robux. A “Skip 10 Tiers” gamepass is also available for 999 Robux, letting you instantly claim the next 10 tiers’ rewards.
Yes. The Nursefather Fedora needed for the evolution is a free track Battlepass reward. No Premium Pass or raid farming required.
The Season 3 Battlepass resets with the next X.0 update (the next major version after Update 3.0). Exact dates haven’t been confirmed — prioritize reaching Tier 50 before Update 4.0 drops.
