Two Machines, One Loop: How Xenogears Fights

Xenogears hides half of its battle system from you. The Xenogears combat system is really two games stacked behind one screen: on foot you spend Action Points on fists and Deathblows, and the moment you climb into a Gear, that economy is swapped out for a fuel gauge and an attack meter you build from scratch. Same turn order, same three attack buttons, a completely different resource underneath — and the game never once sits you down to explain the split.

That doubling is the design, not a bug. Once you can read both economies for what they are — one that banks, one that burns — every fight in the game becomes legible. Here is how each half works, and where the two quietly connect.

One Combat System, Two Economies

Every fight runs on one skeleton. Combat is a version of Active Time Battle: the gauge fills in real time, then stops dead on your turn so you can think. You bring up to three fighters into any battle. The command ring is the same whether you are a person or a forty-foot machine — Run, Item, Defend, Attack, a special-move command, and Combo.

That special-move slot is the first hint the game runs deeper than it lets on. It is renamed for almost everyone who has one: Chi for Fei, Spirit for Rico, Arcane for Citan, Control for Maria, and plain Ether for the rest. Same underlying magic, five different labels, and the game never mentions the pattern.

The split that actually matters is the resource. On foot you spend Action Points; in a Gear you spend Fuel. Everything else — how you learn special attacks, how you chain them, how you reach your strongest state — is the same idea re-skinned for each economy.

There are nine playable characters, and here is the part the roster size hides: each one carries two separate Deathblow lists, one for fighting on foot and one for fighting in their Gear. Nine characters is really eighteen skill tables to fill in. It sounds like more bookkeeping than a nine-person cast should ask for, and it is — but the two lists grow together, so filling one feeds the other.

On Foot: Spending AP, Banking AP

Three buttons, three prices. Every on-foot attack is Weak, Medium, or Strong, mapped to Triangle, Square, and X. Weak costs 1 Action Point, Medium costs 2, Strong costs 3. The harder the swing, the more it costs and the less often it lands — Weak is cheap and reliable, Strong is expensive and misses more.

You start with 3 AP a turn. Leveling raises that ceiling to 6 across the game, and at a fixed point in the story you gain a seventh AP, which is the key that opens the Elemental Deathblows MID-GAME you learn later on.

Here is the part the tutorial skips: AP you do not spend is not wasted. Whatever you leave on the table carries into your next turn and stacks on top of that turn's refill. Tap X to cancel-end your turn early and every unused point drops straight into a separate, larger AP bar — a reserve that sits apart from your per-turn pool. That reserve is the whole reason the on-foot side has a ceiling worth chasing.

One more layer runs alongside AP: Ether, the game's magic. Ether spends its own resource, EP, not AP, and you learn new spells as you level. Worth knowing early — character heals like InnerHealing patch up people, never Gears. The moment you are in a cockpit, that healing does nothing.

Deathblows and the 28-Point Bank

Deathblows are earned, not bought. You do not unlock them from a menu — you learn them by throwing the right sequence of Weak, Medium, and Strong attacks over and over. Progress ticks up in the Status and Skills screen, and once a Deathblow reaches 100 and you have hit its level, it is yours. Fei's first, Raijin, is simply Triangle then X; it arrives around level 5 and costs 4 AP to throw.

From there the inputs and costs climb. Senretsu is Triangle-Triangle-X at level 10 for 5 AP. Hoten stretches to Triangle-Triangle-Triangle-X at level 22 for 6. Koho is a blunt X-X at level 46. Every character has a full ladder like this, and the longer, later entries hit hardest.

When a Deathblow finishes, your turn ends at once — but any AP you had not spent still banks into that reserve. And the reserve climbs all the way to 28. That number is the engine. Once it is loaded, the Combo command spends the whole bank in one go, firing several Deathblows back to back in a single turn with the animation sped up. A full bank is six or seven Deathblows in one uninterrupted string.

That is why a boss with a nasty counterattack is often better burned down in one Combo than chipped at over five turns. If the whole chain lands before its turn comes up, the counter never fires.

Two footnotes the game keeps to itself. The Elemental Deathblows you pick up around level 50 cost 7 AP each and carry one of the game's four elements, and they are the one attack too expensive to fold into a Combo. Fei's own set alone spans Fire and Water . The Earth and Wind versions round it out. And two characters, Maria and Chu-Chu, never get the Combo option on foot at all — their damage comes from elsewhere.

In the Gear: Fuel, Attack Level, and the Deathblow Ladder

In a Gear, there is no AP. Step into the cockpit and the Action Point bar is gone, replaced by a Fuel gauge. Every attack burns Fuel in proportion to its power, and unlike AP, Fuel does not reset between fights — it is a lasting tank you carry from battle to battle. Let it hit empty and your Gear simply cannot attack.

The AP bar has a stand-in too: Attack Level. Each normal attack you throw pushes the Gear's Attack Level up, and it climbs through three steps before topping out at an infinite tier. Attack Level is the gate on Gear Deathblows — level 1 opens the Deathblows that start with a weak hit, level 2 opens the ones that start medium, and level 3 opens the strongest, strong-start ones.

The catch is that spending a Gear Deathblow drops your Attack Level back toward the floor, so you are always rebuilding it with ordinary attacks between big hits. It is the same rhythm as banking AP on foot — patient normal attacks, then a payoff — just measured on a different meter.

Those Gear Deathblows are learned in lockstep with the pilot's on-foot ones, so the eighteen-list problem from earlier is really nine paired lists that fill together. A few Gear Deathblows want more than skill, though: they only fire if the Gear is wearing the matching DeathBlower accessory. Weltall's signature level-1 Deathblow, Raigo, will not come out without a DeathBlower1 equipped.

Two commands keep a Gear alive. Charge makes the Gear defend and claws back 30 Fuel — enough to keep a nearly-dry machine swinging, not enough to actually refill it. Booster is the opposite bet: it works like Haste, speeding your turns up, but it drains Fuel fast enough that it is strictly a boss-fight tool.

And the thing that trips up players coming from other JRPGs: your character level barely touches your Gear's stats. Gears run on their parts, not their pilot's experience bar. Level mostly decides which Deathblows you have access to — grinding EXP to make a Gear hit harder is close to wasted effort.

Hyper Mode: The State That Rewards Nearly Dying

Hyper Mode is the Gear payoff. It opens up after the Shevat dungeon LATE GAME, and it lifts a Gear out of the Attack Level economy entirely: for three turns, every attack becomes an infinite-tier Deathblow, the strongest hits in the game. Put the Holy Pendant on the pilot and that window stretches to six turns. While it runs, Charge stops being a trickle and restores ten times the usual Fuel.

Getting there is where almost everyone misreads the system. You have to push your Gear to Attack Level 3 and hold it — do not spend it down — and then, at the start of each turn, the game rolls a chance to flip you into Hyper Mode. That chance is printed right there in the Gear's status window, and two things push it up: landing Deathblows, and losing HP.

Read that second trigger again, because it inverts the instinct every other RPG trains. A Gear at full health has a low Hyper Mode chance. A Gear beaten down to a sliver has a high one — the more damage you have taken this fight, the likelier you are to flip. Players who heal to full the moment their HP dips are quietly throwing away their best odds of reaching the game's strongest state. Sometimes the right move is to ride the low bar and let the roll come.

The extremes make the rule plain. Fei's final Gear, Xenogears, sits at a permanent 99% Hyper Mode chance — it is built to live in that state. A swordless Heimdal sits at a flat 0% and can never enter at all. Everything else lives on the slope between them, climbing as the fight turns uglier.

Common Questions

How does combat work in Xenogears?

Two economies behind one battle screen. On foot, you spend Action Points on Weak, Medium, and Strong attacks, learn Deathblows by repeating button combinations, and bank unused AP up to 28 to chain those Deathblows with the Combo command. In a Gear, Action Points are replaced by a Fuel tank and an Attack Level meter you build with normal hits to unlock Gear Deathblows. Both run on the same Active Time Battle turn order — the difference is entirely in the resource you spend.

How do you learn Deathblows in Xenogears?

By using them. Throw combinations of Weak (Triangle), Medium (Square), and Strong (X) attacks, and each valid sequence fills a Deathblow's progress in the Status and Skills menu. When it reaches 100 and you have hit the required level, you have learned it. Fei's first is Raijin — Triangle then X — around level 5. The only exceptions are Maria and Chu-Chu, who do not learn ground Deathblows the usual way.

How do you enter Hyper Mode in Xenogears?

Push your Gear to Attack Level 3, hold it without spending it, and let the per-turn chance roll — Hyper Mode unlocks after the Shevat dungeon. The chance is shown in the Gear's status window, and it climbs as you land Deathblows and as your Gear loses HP. That last part matters: a badly hurt Gear is more likely to enter Hyper Mode than a healthy one, so healing to full can work against you. Once you are in, every attack becomes an infinite-level Deathblow for three turns.

Does character level matter in Gear combat?

Barely, for combat power. Your Gear's stats come from its parts, not your character's level, so grinding EXP to make a Gear hit harder mostly does not work. What level does control is which Deathblows you have learned — and since Gear Deathblows are tied to the on-foot ones, leveling still matters for your options, just not for your raw numbers.
