Arena Breakout: Infinite has gone full Biohazard. The crossover with Resident Evil 4 went live on July 24 and it is easily the biggest giveaway the game has run so far: two playable collab characters, six waves of rewards, two new in-raid events and a pile of free items that cost nothing but log-in time.
Here is the full breakdown of what is available, what is genuinely free, and what you should prioritise before the event window closes.
The two collab characters
The headline additions are Leon S. Kennedy and Ada Wong, both deployable as operators in Kamona. They are cosmetic, so there is no stat advantage in a raid, but they come attached to the most valuable part of the event.
At level 30 you receive 3 free character draws, which is the cheapest route to unlocking either of them. Unlock any character during the event and you also pocket the Assault Dagger: Resident Evil Edition as a bonus.
If you are still levelling, getting to Lv.30 should be your single priority this event. Everything else is time-gated, but the free draws are level-gated.
Free rewards, wave by wave
The event is structured as the Biohazard Loot Rush, six waves of rewards running alongside limited-time events. The items that require nothing but logging in:
- Log-in bonus (July 24 to August 5): 5x Golden Gift Boxes, 2x Universal Keys and a 15-day Premium Elite Card
- Free Bonds: log in across 3 days for 1,500 Bonds in total
- Free collab outfit: the Special Security Team uniform, granted on the 7-day log-in track
- Free character draws: 3 draws at Lv.30
- Free red item: the Egg Rally, obtainable through the Egg Trade event
The 2 Universal Keys and the 15-day Elite Card are the standouts. Universal Keys open any locked room, so save them for high-value locations rather than burning them on early loot rooms. If you are unsure which doors are worth it, the interactive maps and the item database will tell you what actually spawns behind them.
Crown of Glory: the million Koen craft
The first of the two new gameplay events is a collection chain. You search raids for Ceremonial Crowns and coloured gems, then combine them into the Crown of Glory, a collectible worth 1,000,000 Koen.
This is a long-tail objective rather than a quick payday. The components drop across raids, so treat crowns and gems as opportunistic pickups while you run your normal routes rather than something to hunt specifically.
Egg Trade: the one worth learning
The Egg Trade is the more interesting event mechanically, because it behaves like a small trading market rather than a loot checklist.
You loot eggs across all maps and trade them using merchant clues to earn Spinels. The catch is that prices fluctuate daily and trades carry risk multipliers, so the same egg is worth very different amounts depending on when and how you sell it.
Spinels convert into sprays, badges, the Infection Variation Vector 9 SMG and the full Crest Lord collab outfit (hat, jacket, pants and boots).
Two practical notes. First, check the daily prices before you commit a stack of eggs, since holding a day can be worth significantly more. Second, the Egg Rally, the limited-time red item, spawns from safes on all maps in the Dark Zone, so safes are worth the time cost this event even when you are running light.
Twitch Drops: three exclusive throwables
Running from July 24, watching participating streamers with Twitch Drops enabled earns three exclusives you cannot get in game:
- Twitch Exclusive Stun Grenade
- Twitch Exclusive Tear Gas
- Twitch Exclusive Flashbang
These are skins rather than new tactical items, so they behave exactly like their standard versions. If you want to know what each throwable actually does before you commit a slot to one, the throwables section of the database lists fuse delays, ranges and effects.
What to do first
If you only have limited playtime this event, the order that returns the most value:
- Log in every day, without exception, for the Bonds, the outfit and the Elite Card
- Push to Lv.30 to unlock the 3 free character draws
- Loot safes on every run while the Egg Rally is active
- Bank eggs and sell into a high price day rather than trading immediately
- Save the 2 Universal Keys for genuinely high-value rooms
The collab runs alongside the existing Season 6 content, so the Season 6 mission tree keeps progressing normally while you farm the event. Nothing here is exclusive to one or the other.
