At some point, your fleet will appear on someone else's threat map. Maybe you've expanded into territory they wanted. Maybe your trade convoy ran through a corridor without paying the toll. Maybe someone just decided you looked like a viable target.
PvP in Starforge is not optional in the long run. It is also not the terror that new players tend to assume it is. Understanding how combat works — the actual mechanics, not the feeling — removes most of the fear and replaces it with something more useful: calculation.
This guide is for commanders who have never initiated a PvP engagement and aren't sure they want to. You will fight eventually. You might as well understand what you're doing.

The First Decision: Should You Fight at All?
Before any engagement, before you commit ships to a fight, you need to answer a single question: what does winning get me, and what does losing cost?
PvP in Starforge is not symmetric risk. The attacker chooses the engagement; the defender is surprised. The attacker has already calculated (or should have) that the odds favour them. If you are the one being attacked, the baseline assumption is that your opponent believes they can beat you. That doesn't mean they're right. But it means you should not assume the fight is equal.
The default answer to "should I fight?" in your first month of play is: probably not, unless you're defending your core sector.
Defending your home sector — the one with your primary infrastructure — is worth committing everything you have, because the cost of losing it (50% of stored resources looted, infrastructure transferred to the enemy) is greater than the cost of losing your fleet. Your fleet can be rebuilt. A captured developed sector takes weeks to reconstruct.
Defending an outlying sector is a different calculation. If you have a Tier 1 outpost sector with minimal development, losing it costs you less than losing a fleet of mid-tier ships trying to defend it. Retreat and rebuild. Don't let pride make the decision for you.

Newbie Protection: What It Does and Doesn't Do
Newbie Protection prevents commanders with significantly higher fleet power from initiating siege operations against your sectors. Specifically, anyone more than two tier-bands above your fleet power cannot siege your controlled sectors.
What protection covers:
- Siege initiation against your sectors by powerful attackers
- Conquest by established players who vastly outscale you
What protection does NOT cover:
- Open-space fleet engagements (anyone can attack any fleet in open space, protection or not)
- Players at similar fleet power to you — protection only blocks large mismatches
- Piracy of your trade convoys
When protection ends: 15 days account age, OR fleet power crosses the Tier 2 threshold, OR you attack another player's sector — whichever comes first. Initiating aggression immediately voids your protection. This matters: do not raid another player's sector while you're still in the protection window if you're not ready to defend your own sectors without it.
Use the protection window to fortify. Build your 3 Orbital Platforms and 2 Shield Generators before protection expires. That combination makes your sector expensive enough to siege that opportunistic attackers will look for softer targets.

Reading a Battle Report
After any PvP engagement — whether you initiated it or were the defender — you receive a Battle Report. New players often read these wrong, which leads to bad conclusions about whether the fight was worth it.
A Battle Report shows:
Fleet compositions (attacker and defender ships at the start of engagement, by type and tier)
Combat rounds — each round is one exchange of fire. The combat system runs up to 20 rounds maximum, with each round applying the damage formula: attacker.attack × fleet_size − defender.armor × 0.5. Rounds resolve simultaneously; there's no turn order within a round.
Module type interactions — the report flags when kinetic weapons faced shields (+50% damage to shields), or energy weapons faced armored hulls (+50% damage to armor). These interactions can swing a fight significantly.
Losses by ship class — what was destroyed on each side, by type. This is the number you actually need to look at.
Loot collected — 50% of the defender's stored resources in the sector, if the sector was captured or raided. This appears only when resources were actually collected.
Salvage available — coordinates where module salvage from destroyed ships can be recovered. 30% of destroyed modules are recoverable as salvage. Send a fleet to collect them.
The combat round log in the expanded view shows you exactly when and why the battle outcome was decided. High-round counts (15-20 rounds) indicate a closely matched fight. Low-round counts (1-5 rounds) indicate a significant mismatch. If you're consistently losing in 3 rounds, the problem is not tactics — it's fleet power disparity.

The Loss Calculation: When Is a Fight Worth It?
This is the question experienced commanders always ask before an engagement, and new players almost never do.
The basic calculation:
Expected gain: What you get if you win (resources looted at 50%, sector infrastructure if capturing, strategic position value).
Expected loss: What your fleet costs to replace if you lose (at your current tier, roughly 12% of build cost in resources for full repair on surviving ships, full replacement cost for destroyed ships).
Win probability: Estimated from fleet power comparison. Equal fleet power = approximately 50% win rate. Each 20% power advantage = roughly 15% increase in win probability.
If expected gain × win probability > expected loss × (1 − win probability), the fight is economically rational.
A worked example: You're considering raiding an outlying Tier 2 sector with estimated 40,000 Metal and 20,000 Crystal stockpile. To loot it you'd collect 50%: 20,000 Metal, 10,000 Crystal. Your fleet has 30% power advantage over the defender, estimating ~65% win probability. Your fleet replacement cost if you lose is 25,000 Metal, 12,000 Crystal.
- Expected gain: 20,000 Metal × 0.65 = 13,000 Metal; 10,000 Crystal × 0.65 = 6,500 Crystal
- Expected loss: 25,000 Metal × 0.35 = 8,750 Metal; 12,000 Crystal × 0.35 = 4,200 Crystal
Net positive on both resources. The raid is economically rational.
You don't need to run this math in your head for every fight — but calibrating this instinct is what separates commanders who grow their empires from commanders who stall because they keep making unprofitable fights.

Reputation and Piracy Mechanics
Every aggressive action in Starforge affects your reputation with one or more factions. Understanding what reputation costs you is part of the engagement calculation.
Alliance-declared war: When your alliance formally declares war on another alliance (costs 50,000 credits), combat between the two alliances is reputation-neutral. You can attack their fleets, siege their sectors, and raid their convoys without reputation penalty. This is the intended high-stakes PvP mode.
Piracy: Attacking fleets or convoys outside a formal war declaration, or raiding sectors owned by players your alliance is not at war with, counts as piracy. Each piracy action reduces your reputation with the Commerce Authority and the targeted player's affiliated faction.
Reputation consequences:
- Moderate reputation loss: certain faction technology blueprints become unavailable for purchase until reputation recovers
- Significant reputation loss: bounties are posted — other commanders receive a credit bonus for destroying your fleet
- Severe reputation loss: some faction stations refuse docking rights, blocking repair and resupply in those locations
Reputation recovers over time (passive recovery: approximately 50 points per day) and through specific reputation-positive actions: paying the toll at Syndicate corridors, completing commerce escort missions, participating in anti-piracy responses. You can recover from a piracy history, but it takes time and intentional effort.
Some commanders build intentional piracy-focused playstyles, usually Iron Dominion renegades or Void Syndicate corridor operators. This is viable, but requires accepting the trade-off of restricted faction access and occasional bounty fleets. It's not a mistake — it's a playstyle choice with real costs.

Fleet Composition for PvP vs. PvE
New players often use the same fleet for everything. This works early on, but PvP and PvE encounters have meaningfully different optimal compositions.
PvP engagements against other players trend toward:
- Faster, higher-damage ships with moderate armour (you want to win before their modules compensate for your attack)
- Modules with kinetic weaponry if your opponent favours shields (the +50% damage bonus matters enormously in close matchups)
- Retreat capability — having ships that can survive and escape a losing engagement preserves fleet value
PvE encounters (pirate bases, roaming hostile fleets, boss encounters) trend toward:
- High-health, high-armour vessels that can absorb repeated damage without retreating
- Energy weapons for armoured targets (bosses typically run high-armor low-shield loadouts)
- Sustained DPS over burst damage — boss fights go more rounds than PvP typically does
If you're preparing for your first PvP engagement, audit your module loadout against the likely enemy composition. A fleet optimised for killing Tier 2 pirate bases may be poorly equipped for fighting another player using a shield-heavy Iron Dominion formation.

Practical PvP for Your First Three Months
Month One: Don't initiate PvP outside protection windows. Fortify your core sector. Build defensive infrastructure, not offensive ships. Learn to read the galaxy map for incoming threat indicators.
Month Two: Your first voluntary PvP should be a low-stakes raid on an undefended or lightly defended outlying sector — not because it's heroic, but because it's the lowest-cost way to practice reading battle reports and understanding the engagement flow without risking a core sector.
Month Three: You have enough data to understand your fleet power relative to neighbours. Identify which engagements are favourable and which aren't. Join your alliance's next declared war engagement — fighting inside a formal war declaration removes the reputation cost and lets you learn from experienced alliance commanders.
The commanders you'll eventually respect most in this game are the ones who fight carefully and rarely, not the ones who fight constantly and expensively. Aggression without calculation is just resource destruction wearing a combat skin.
Fight well. Fight when it makes sense. And when it doesn't make sense — turn around and rebuild.
