Serious Sam HD: The First Encounter is Croteam’s high-definition remake of the original ancient Egypt arcade shooter. This guide is for the HD First Encounter campaign, not the 2001 Classic release by itself, HD: The Second Encounter, Classics: Revolution, the VR version, Fusion as a hub, or a collection bundle unless your edition clearly labels the same First Encounter HD campaign.
Content warning: This is a mature first-person shooter with blood/gore and violence. The advice below keeps those themes non-graphic and focuses on how to play.
The game is simple on paper: move fast, read the arena, pick the right weapon, and survive large groups. The challenge is doing all of that while enemies attack from several ranges at once.
Essential Tips
1. Keep Moving, but Move With a Plan
Standing still is dangerous, but drifting is not strategy.
Serious Sam wants constant movement because many fights are built around enemies closing distance, firing from range, or entering from more than one side. Circle-strafing and backward movement help, but do not stare only at the enemy directly in front of you. Pick a section of the arena, keep open space behind or beside you, and avoid backing into corners, pillars, walls, or pickup traps.
When a fight opens up, note exits, wide lanes, pickup clusters, and threats that can reach you quickly. Then move deliberately. Running without awareness turns every arena into a panic lap.
2. Listen for Threats Before You See Them
Audio cues are part of the battlefield.
Enemies often announce themselves before they are comfortably visible. If you hear pressure from behind, do not instantly spin away from the whole fight and lose track of the crowd. Strafe away from the sound, create space, and bring the threat into view when it crosses your line. This habit keeps you from giving ranged enemies free shots while you chase one fast target.
3. Read Arenas as Supply Rooms
Ammo, health, armor, and power-ups are part of the encounter design.
Large pickup clusters usually mean the game expects a fight, not that you should vacuum everything up at once. Enter with enough health and ammo to start cleanly, then leave recovery options if you can. If you grab every item early, later damage has no cushion.
The same rule applies to armor. It absorbs damage only after you pick it up, so timing matters. If your health is stable, consider whether nearby armor will help more after the opening exchange.
4. Use NETRICSA When the Game Offers It
The in-game information tool is easy to ignore.
NETRICSA messages can appear when you enter areas, find weapons, or encounter enemies. Read them during quiet moments. They often explain enemy or weapon behavior in a way that matters more than another few seconds of sprinting forward.
This is especially useful on a first clear because the game teaches by pressure. When a new enemy type appears, knowing its broad role helps you decide whether to kite it, burst it, dodge it, or keep it at range.
5. Save Around Fights Where Your Edition Allows It
Use saves to learn, not to brute-force bad habits.
On PC-style versions with quicksave or manual save options, save before major arena pushes and after clean wins. That protects you from losing a good clear to one late mistake. Avoid saving while trapped, surrounded, or seconds from damage.
Console and collection editions can differ, so check your pause menu and load menu early. Whatever your edition uses, build the same rhythm: enter prepared, survive the fight, stabilize, then save or confirm progress before rushing into the next trigger.
6. Treat Secrets as Optional Power, Not the Plan
Hidden items can help, but this is not a secrets route.
The campaign includes secrets with weapons, ammo, power-ups, traps, enemies, jokes, or mixed rewards. On a first run, take obvious secrets when you find them, but do not build your survival plan around knowing exact hidden locations. A strong beginner route should work because your movement, target priority, and ammo habits are improving.
Weapon and Pickup Priorities
7. Keep the Revolvers Relevant
Infinite ammo is a real tactical advantage.
The revolvers are not your strongest damage option, but they are useful for weak enemies, distant cleanup, and moments when you should not spend better ammo. If a small target is not an immediate danger, revolvers can preserve shells, rockets, bullets, or cannon shots for the next arena.
8. Match Shotguns to Distance
Close-range weapons lose value when you force them into the wrong job.
The pump shotgun is comfortable for steady close or mid-close work, while the double-barrel shotgun is better when something dangerous is already near you. Do not chase far targets with shells if another weapon can handle them cleanly.
9. Spend Automatic Fire With Intention
Fast weapons solve problems quickly and drain reserves quickly.
The Thompson and minigun are strong when you need stable pressure, but they can empty your ammo stock if you hold the trigger through every small target. Use automatic fire when the target count, distance, or threat level justifies it.
10. Respect Explosive Self-Damage
Rockets and grenades punish panic shots.
Explosives are excellent against groups and heavier targets, but tight rooms, close enemies, and sudden strafes can turn them against you. If a fast enemy is already close, swap weapons or move first. Do not fire a rocket just because it is selected.
11. Save Heavy Shots for Heavy Problems
The cannon is not just a victory noise.
The cannon can pierce through groups and punish strong enemies, making it valuable when a fight lines enemies up or when a bigger target needs to disappear. Avoid spending it on scattered weak enemies unless the situation is getting out of control. The best heavy shot usually solves several problems at once.
12. Let Ammo Backpacks Warn You
Big ammo pickups often forecast big pressure.
When you see major ammo support before an open space, slow down and prepare. Reload what needs reloading, check health and armor, pick your opening weapon, and look for movement lanes. The game often gives you enough supplies to survive if you read the room.
Co-op and Difficulty Habits
13. Divide Jobs in Co-op
Four players shooting one distant target can still lose to one close pack.
In co-op, do not stack everyone’s attention on the same enemy unless it is the only serious threat. One player can pressure heavy or distant enemies while another clears fast close-range attackers. Keep calling out danger from behind and avoid blocking each other’s retreat paths.
If one player has more health and armor, that player can take the first look into a risky area. The rest of the team should be ready to cover.
14. Expect Co-op to Add Pressure
More players does not mean the campaign becomes effortless.
Campaign co-op can add enemies or change enemy durability depending on settings and edition. Treat co-op as shared arena control, not a race for kills. Watch backs, share pickups sensibly, and keep enough spacing that one explosion, charge, or leap does not punish the whole group.
15. Choose Difficulty for Learning
A clean clear teaches more than repeated frustration.
Higher difficulties can increase enemy pressure and make mistakes expensive. Start where you can learn enemy roles, weapon swaps, and arena flow without turning every room into a reset. Move up once you react to sound cues and clear arenas without scrambling.
Serious difficulty is a separate commitment. It changes how much pressure you face and makes careless self-damage, item grabs, and weapon choices much harsher. Learn the campaign before treating it like a challenge route.
Common Mistakes to Avoid
-
Do not stand still while aiming - Keep strafing so charging enemies and projectiles have to work for damage.
-
Do not backpedal without checking space - You can survive one enemy and still lose by backing into a wall or corner.
-
Do not spend every pickup before the fight starts - Leave health, armor, or ammo available when the arena allows it.
-
Do not use one favorite weapon for every target - Revolvers, shotguns, automatics, explosives, and cannon shots all solve different problems.
-
Do not fire rockets at point-blank range - Move or swap before self-damage turns a manageable enemy into a reset.
-
Do not ignore NETRICSA messages - They can explain new threats and weapons before pressure ramps up.
-
Do not save while already doomed - Save before a risky push or after a clean win, not during a bad panic moment.
-
Do not chase every secret on a first clear - Learn arena flow first; exact hidden-item routing belongs in a separate route.
-
Do not bunch up in co-op - Spread jobs and sightlines so one threat does not punish the whole team.
-
Do not jump straight to Serious difficulty for pride - Learn the campaign’s rhythm before adding harsher pressure.
