Starship Troopers: Ultimate Bug War! on PC and consoles drops you into a solo FPS campaign where you lead Mobile Infantry squads against Arachnids using the Morita rifle, heavier weapons, tactical support, and even mechs. On day one, the best “classes” are really loadout archetypes built around confirmed weapons and tools from the demo and official previews: an all‑round Morita Rifleman, a close‑range Breacher, a Demolitions specialist, and a mobility‑focused Scout.
If you just want a fast answer: start the campaign with a Morita‑centric Rifleman build, grab a shotgun or battle rifle as a backup, use grenades and support items to control big swarms, and save heavy explosives for AA Bugs and nests. Once you’re comfortable, lean into Breacher or Demolitions loadouts for objective missions, and experiment with mobility‑heavy routes on replays to chase secrets and faster clear times.
Quick steps: how to build a strong day 1 loadout
-
Start with the Morita rifle and keep it as your main gun until you know Bug health and recoil well.
-
Pick up a shotgun or scoped rifle when you find one to cover close or long range gaps.
-
Equip grenades and use them on nests, siege cannons, and dense clusters instead of lone Bugs.
-
Use supply crates and drop‑style support items whenever you’re low, not just in emergencies.
-
Save heavy explosives for mission objectives like Bug siege cannons and AA structures.
-
On replay, adjust difficulty and route order in the mission briefing to suit your preferred playstyle.
How classes and loadouts actually work in Ultimate Bug War
The campaign is a classic retro‑style FPS where you play as a Mobile Infantry trooper leading squads across large, open battlefields with multiple objectives you can tackle in any order. You don’t pick a formal class at a menu; instead, the game lets you define roles through your weapon choices, support items, and how you approach each mission.
Official descriptions confirm a “devastating anti‑Bug arsenal” with over 30 weapons and items across the full game, though the campaign itself is framed around 14 core weapons including the Morita rifle, heavy guns, and tactical support. The demo and gameplay previews show rifles with different ranges and fire rates, grenades, flares, tactical air support, gunship segments, a tactical nuke‑like strike, and the Razorback mech with a machine gun and chainsaw arm.
From that, four clear day one archetypes emerge for the Bug War campaign.
Morita Rifleman – the safest starting “class”
The Morita assault rifle is your default weapon and the backbone of early missions, with reliable mid‑range damage and a fast‑firing feel that suits the game’s high‑tempo bug waves. It appears across all marketing material as the iconic Starship Troopers gun, and you’ll drop into missions with it before collecting alternatives on the field.
Recommended Rifleman setup
-
Morita rifle as primary
-
Shotgun or scoped rifle as secondary pickup when available
-
Frag grenades
-
Flares or equivalent support to call in resupplies or tactical support (as shown in demo footage)
This build covers almost every situation in the first few missions, letting you learn Bug behavior, map layout, and objective flow without juggling niche weapons. You trade raw burst damage for consistency, which is perfect for new players and anyone coming back to boomer shooters after a break.
Breacher and Demolitions – best early‑game objective builds
Once you’re comfortable with basic gunplay, you can lean into close‑quarters and explosive tools that the demo highlights during AA Bug and siege cannon objectives.
Close‑quarters Breacher
A Breacher‑style loadout focuses on shotguns and aggressive objective defense.
-
Shotgun‑focused loadout, with Morita or another rifle as backup
-
Explosives (grenades or satchel‑type items when available)
-
Extra health/armor pickups via support where possible
This shines in interior fights, chokepoints, and final defense waves, where a generous shotgun range and high damage per shot can erase Warriors and smaller Bugs quickly. The trade‑off is that you’re weaker in wide‑open, long‑range engagements and depend heavily on good positioning and ammo management.
Demolitions specialist
Several demo segments and previews show you destroying Bug siege cannons and nests with explosives, which naturally supports a Demolitions flavor of play.
-
Morita or heavier primary weapon
-
Satchel charges or mission explosives (when the mission provides them)
-
Grenades specifically reserved for nests, cannons, and dense clusters
-
High‑impact tactical support like bombing runs, gunship sequences, or a tactical nuke‑style strike when unlocked
Demolitions builds excel at clearing mission‑critical structures and cleaning up big waves, but you sacrifice some flexibility between big detonations. You’ll enjoy this if you like planning your pushes and timing huge plays rather than constantly holding the trigger.
Mobility Scout and secrets – playing the map your way
Starship Troopers: Ultimate Bug War lets you choose difficulty and, in the demo mission, order objectives as you see fit, which naturally rewards a more mobile, routing‑focused style once you know the layout. Demo impressions describe larger open maps where you move between Bug assaults, AA cannons, and nests, with secrets and replay value baked in.
A mobility‑driven “Scout” style isn’t a formal class, but you can build into it:
-
Lightweight rifle (Morita or similar) without over‑committing to slow heavy weapons
-
Frequent use of sprint and strafing to cross open ground between Bug waves
-
Proactive use of supply crates placed at strategic points, rather than fighting near empty magazines
-
Rerunning missions at higher difficulty and experimenting with different objective orders for better routes
This style suits players who like speedrunning and exploration. You give up some raw power compared to running heavy gear every time, but in return you get faster progress, better map knowledge, and more consistent resource usage.
Mech segments and heavy support – when you become the hardware
The arsenal shown so far includes not just infantry guns but also the M7 Razorback mechanical biped, a mech with a machine gun and a chainsaw arm. Preview footage notes that the Razorback has limited fuel and self‑destructs when it runs out, dealing huge damage in an explosion that can also injure your own squad if they’re too close.
Mech segments essentially flip you into a temporary “Heavy” class:
-
High sustained fire from the mech’s machine gun for clearing hordes and destroying nests
-
Chainsaw arm for brutally effective close‑quarters Bug control
-
Self‑destruct that doubles as an emergency nuke when you’re out of fuel
The downside is that these sequences are time‑limited and scripted within missions, so you can’t rely on them as your default class. Instead, think of them as reward spikes and plan to make the most of them when they appear.
Bug Mode forms – Assassin Bug “classes” on the Arachnid side
Outside the main campaign, Bug Mode lets you play as the Assassin Bug across four training environments, controlling the Arachnid side for a series of Terror Zones. Official trailers and the Bug Mode reveal confirm that the Assassin Bug can switch between three forms: Warrior, Hopper, and Tanker.
Bug Mode also gives the Assassin Bug pheromone spray to direct nearby Bugs and recruit new allies from Bug nests, turning you into both a frontline attacker and a battlefield commander. If you enjoy this side mode, you can treat each form as a different “class”: aggressive Warrior pushes, surgical Hopper dives, and slow, crushing Tanker assaults.
Which day 1 loadout should you pick?
If you’re brand new to Starship Troopers: Ultimate Bug War on March 16, 2026, stick with a Morita Rifleman setup until you’ve cleared the first mission or two. The gun is forgiving, ammo is easy to understand, and it pairs well with every utility the game throws at you, from grenades and flares to mech segments and tactical support.
From there:
-
Shift into Breacher or Demolitions builds for objective‑heavy maps with nests and siege cannons.
-
Try a more mobile approach on replays once you know where supply crates and chokepoints are.
-
Jump into Bug Mode when you want a break from trooper duty and a different style of “class” in the Assassin Bug’s forms.
