How to Unlock Bowler NPC in Enter The Gungeon

Enter The Gungeon’s final update, A Farewell to Arms, introduces a new NPC, Bowler, along with several new weapons, items, and characters. If you’re wondering how to unlock Bowler, this guide will walk you through the process step by step.
1. Start a Run and Look for a Locked Cell
After installing the update, begin a new run in Enter the Gungeon. As you clear floors, keep an eye out for a locked cell. Inside this cell, you’ll find Bowler, the new NPC.
2. Find the Cell Key
Unlock Bowler by obtaining a Cell Key, which can drop from any random enemy, including the floor boss. Once you have the key, return to Bowler’s cell and use it to free him.
3. Speak with Bowler to Unlock Him
Once Bowler is freed, speak to him. After your conversation, Bowler will make his way to the Breach, the central hub area where NPCs are located.
4. Access Rainbow Runs with Bowler
Now that Bowler is unlocked, you can speak with him in the Challenge Run Room (located to the right of the main entrance to the Gungeon). He will offer you the Rainbow Run game mode.
In Rainbow Runs, you begin each floor with a single Rainbow Chest, which contains one item. This is the only item you will receive for that floor, so choose wisely. No other items will be dropped during that run.
That’s all you need to know about unlocking Bowler and starting Rainbow Runs in Enter The Gungeon’s A Farewell to Arms update. Enjoy the challenge of limited item pickups and test your Gungeon skills!
