Bit Kid’s roguelite Metroidvania Chasm has just received its first free content pack.

The Guilean Arcade Pack adds the new Arcade Mode, which takes the game’s procedural generation to its logical extreme. Instead of the entire world being generated upon starting a new run, in Arcade Mode the game generates rooms on the fly, meaning that you can leave a room, come back, and it’ll be completely different.

You are also on a strict time limit, and are only allotted 8 minutes to explore an area before you die and your run ends. The Arcade Mode is actually three modes in one, with Daily Challenges, Weekly Challenges, and a Practice Mode.

The update also features a number of combat enhancements, which you can read more about here. You can check out the launch trailer above.

Here’s a rundown of the new modes:

It’s 1992, and the arcade is the place to be for the most advanced and challenging experiences around. A mysterious new game has appeared that has all the kids at school talking. This game is different every time you play it, and the leaderboards reflect only those with the quickest wits to combat its twisting dungeons, ferocious enemies, and unpredictable nature.

When people first play Chasm, many don’t realize that there is a robust world building engine powering it. After all, it plays like a good old fashioned dungeon crawling Metroidvania. We had tons of ideas of ways we could leverage the procedural dungeon creation engine, so we set to work and built our first DLC for Chasm: the Guilean Arcade Pack. And best of all, it’s free!

Unlike the main mode, which generates a full world map when you start up your campaign, the new Arcade Mode generates a new layout of the world on the fly. Leave a room and come back, and it’ll be a completely new room. You have 8 minutes to explore each area of the world. If you don’t reach the next area or die along the way, your game is over.

The Arcade Mode is really three modes in one:

• Daily Challenge: Every day you get one shot to leave your mark on Karthas history. Stay alive, progress as far as you can, and rack up your kill count and reach the next area as quickly as possible for maximum points to earn your spot at the top of the daily leaderboard.
• Weekly Challenge: Same idea as the Daily Challenge, but you can take your time and get to know the map. Play through as many times as you like, finding the best shortcuts, loot, and power-ups along the way. Your highest score for the week will be recorded for posterity.
• Practice: No one’s keeping score but you, so just have fun in this mode. Use the randomly generated seed to explore a new dungeon just for you, or enter your own seed number to explore a dungeon you’re already familiar with.

Chasm is available on Windows PC, Mac, and Linux (all via Steam and the Humble Store), PS4, Vita, and the Switch for $19.99. It should be noted that the new content is only available on the Steam version right now, which is currently 10% off as part of the Halloween Sale.
