Dev Updates & Bits

Launched just two days ago (I couldn’t post earlier), the new chess clock and timeout patrol system are now officially active – and they’ve completely changed the mood of matches!

Each player now has their own action timer, bringing real time pressure to every turn. If you hesitate too long, the patrol will automatically take action. This simple change made competitive mode feel way more serious, tactical, and exciting. It’s honestly amazing how much difference the clock makes – matches feel faster, cleaner, and every decision counts.

Current settings are: 20 minutes per player and 60 seconds per action. I’m thinking about changing competitive mode to 15 minutes / 40 seconds – what do you think? Leave your thoughts and feedback in the comments below!

Along with this, I’ve added several quality-of-life improvements: counters now display your level, resources, deck, trash, and shield counts when you move the mouse over them, plus server upgrades for smoother performance and lower latency, and minor fixes and polish all around to keep matches running stable and enjoyable.

So yeah! competition just got real. try the new clock, feel the pressure, and sharpen your skills!

Cheers, Doug – dev & time sheriff!

Hey everyone! Quick feedback about the new Competitive mode — it really seems to be working out well!

I played several matches in Competitive yesterday and today, and it was extremely satisfying. Great opponents, fast games, and strong plays all around. It truly feels like players are taking this mode seriously — and it’s awesome to see!

I also played a few rounds in Casual mode, and it’s perfect for testing my own cooked builds or just playing for fun and chill.

After all, competition is in the blood of every true Gundam fan — testing your skills, adapting, and evolving with each battle is what this game (and the series itself) is all about.

Some people have asked about a ladder/ranked mode — I think it’s not quite the right time yet, as I’m still focused on finishing key features and important quality-of-life improvements. But don’t worry, that’s already part of November’s priority list!

If you haven’t tried it yet, I highly recommend giving it a shot. Whether you’re testing decks in Casual or climbing for glory in Competitive, the experience just keeps getting better.

See you on the battlefield!

Cheers, Doug - dev & sword striker!
