Trillion: God of Destruction is a PS Vita strategy game where you must stop a demon, Trillion, who seeks to consume the whole Underworld. The catch? Trillion’s got one trillion HP. You’ve got six Overlords to defeat him. In your first playthrough, not all of them will survive.

So how exactly do you beat a boss with 1,000,000,000,000 HP? I’m here to give you an overview of what it means to prepare for a boss like this.

I’ve played all kinds of great strategy games, from Phantom Brave to Valkyria Chronicles. But with about 50+ hours of gameplay, none have had a longer, more punishing final boss battle than Trillion. But that’s my favorite thing about Trillion — a large portion of gameplay is done not only on the battlefield, but off it, during preparation.

Despite the strategy RPG label, Trillion also has strong raising sim elements, because you must train your Overlord and customize her stats.

Trillion consumes the Underworld by day, but sleeps after some period of eating. While he’s asleep you must cycle through training, rest, and socialization to improve your Overlord’s overall stats, maintain her condition, and raise your affection points!

Sound easy? Well, Trillion: God of Destruction was developed by talented SRPG masterminds, so when they say strategy game, they mean it! And in Trillion, preparing for battle is more like playing with the cards you’ve been dealt.

For example, training awards stat points that you can add onto your Overlord’s stats to change up her fighting-style. However, the amount of stat points you earn isn’t guaranteed. Just like in real life, some days training is “Good,” other days it’s “Excellent,” and if your Overlord works too hard without rest, you’ll get a “Bad” and she risks injuring herself.

Overall, here’s the game flow:

First you train in whichever training regime to earn stat points, and then afterwards you allocate those points to your Overlord’s stats. Training takes up the whole day and if you do great or excellent, you earn a Training Medal that you can use to enter the Valley of Swords.

If you train everyday, your Fatigue gauge will fill. To relieve Fatigue, you can choose to Rest for the whole day. By Resting, you’ll be able to do a number of things: Sleep, Interact, Order, or Underworld Prize.

One of the most important options here is Interact. You can spend time with your Overlord and build her Affection Points for you, which will be useful in battle but also determine which ending you will earn.

After some training and enough Training Medals, you have a shot at the Valley of Swords, where you can find items and earn more EXP!

Finally, visit the research lab to hire Devil Envoys as assistants on the battlefield and the Blacksmith to customize your weapon. Now you’re set to fight Mokujin, a Trillion-replica made by Faust, the necromancer who revived you!

After the whole cycle ends, set equipment and items and the true battle with Trillion starts!

But no matter how much you’ve prepared your Overlord, there’s a strong chance she won’t make it… And the training cycle will begin again with a new Overlord.

We’ve only scratched the surface of it, but there are tons more game mechanics to cover like romance/dating elements, skills and stats inheritance, and Trillion’s different evolutions.

What do you think of this unique preparation cycle? Let’s discuss in the comments!
