Mastering Tactical Plugins in Last Z: Survival Shooter
Updated October 12, 2026
Tactical Plugins: Enhancing Your Last Z Vehicles
In Last Z: Survival Shooter, Tactical Plugins are crucial for boosting your vehicle's performance. Each vehicle in a formation is equipped with four distinct plugin slots, tailored to its specific faction. These powerful enhancements range from 0★ to 8★, requiring a significant investment of resources for maximum potency.
To elevate a single orange-quality plugin from 0★ to its 8★ pinnacle, you'll need a total of 58,486,700 Plugin EXP, 57 identical copies of that specific plugin, and 20 catalysts. The progression of star-up expenses remains consistent across all faction sets.
Each star level is segmented into eight distinct markers. Plugin Resonance, a vital bonus, is determined by the lowest star level among the four orange plugins currently installed.
Understanding Tactical Plugins
Plugins are associated with a formation's vehicle, with distinct sets corresponding to each faction. The four available slots are:
- Opening
- Offensive
- Defensive
- Jamming
It's essential to equip a plugin set that matches the vehicle's current faction. Should a vehicle's faction be altered, its currently installed plugins will be automatically unequipped.
Plugin stars from 1★ to 5★ are visually represented in gold, while 6★ to 10★ turn red sequentially. Star progression uses universal Plugin EXP or EXP obtained by dismantling green, blue, and purple plugins. The initial material gate at 1★ requires 20 catalysts, with subsequent gates demanding exact duplicates of the orange plugin being upgraded. Orange plugins cannot be consumed for EXP; they are reserved for their own advancement or to satisfy duplicate requirements.
The Four Orange Plugin Slots at 8★
The following examples detail the 8★ statistics and effects using item names from the Wings of Dawn set. Other faction sets feature equivalent slots, identical star costs, and numerical impacts, with the named hero bonus adjusting based on the set.
| Slot and Example | 8★ Stats | 8★ Skill Effect |
|---|---|---|
| Opening · Ultra EM Shield IV | Faction heroes' ATK +2,524; Troop HP +12.4% | Battle-start shield (factor 440) for 2 seconds; 8.6% less normal and counterattack damage to the troop |
| Offensive · Ultra Fire Amplifier IV | Faction heroes' ATK +2,524; Troop ATK +62% | Normal and counterattack damage +13%; 26% chance to recast after the vehicle skill |
| Defensive · Ultra Capacitor Armor IV | Faction heroes' DEF +2,524; Troop DEF +62% | Troop damage reduction +13%; after the vehicle skill, faction heroes gain 13% damage reduction for 3 seconds |
| Jamming · Ultra Electro Pulse IV | Faction heroes' DEF +2,524; Troop DMG +24.8% | Enemy heroes' skill damage −13%; own faction heroes' in-troop skill damage +25.9% |
Each orange plugin contributes 174,000 power at 0★ and a substantial 1,150,000 power at 8★. The secondary stat progression is divided across eight steps per star: Troop HP increases from 0.4% to 12.4%; Troop ATK and DEF use a track five times larger (2% to 62%), and Troop DMG follows a track twice as large (0.8% to 24.8%). Skill effects also scale with star levels; for instance, the shield factor gains 30 points per star.
Star-Up Mechanics: Eight Markers Per Star
Each star level comprises eight markers. Standard markers require EXP, while diamond markers signify material gates. Both EXP and gate markers within a star provide identical stat and power boosts, ensuring plugin progression even if a star isn't fully completed.
| Target Stars | Eight-Marker Sequence | Material Gates |
|---|---|---|
| 1★–2★ | 7 EXP → final gate | 1 final gate |
| 3★–4★ | 4 EXP → gate → 2 EXP → final gate | 2 gates |
| 5★–9★ | 2 EXP → gate → 1 EXP → gate → 2 EXP → final gate | 3 gates; 9★ copy costs are currently undetermined |
The final gate for 1★ demands 20 catalysts. Subsequent gates necessitate exact orange plugin duplicates. The final gate alone requires 1 copy at 3★, 5 at 6★, 8 at 7★, and 10 at 8★; additional gates within these stars account for the remaining copy requirements.
Full Star-Up Costs from 1★ to 8★
This table outlines the costs for upgrading any orange Tactical Plugin in any faction set. "Stat per marker" refers to the faction hero ATK or DEF gained at each of the star's eight markers, while "power gained" indicates the total increase across that entire star.
| Target | EXP for Star | Exact Copies | Stat per Marker | Power Gained | Total EXP from 0★ | Total Copies from 0★ |
|---|---|---|---|---|---|---|
| 1★ | 129,500 | 0 + 20 catalysts | +12 | 56,000 | 129,500 | 0 |
| 2★ | 512,000 | 1 | +16 | 64,000 | 641,500 | 1 |
| 3★ | 1,266,300 | 2 | +24 | 96,000 | 1,907,800 | 3 |
| 4★ | 3,195,700 | 3 | +24 | 96,000 | 5,103,500 | 6 |
| 5★ | 5,292,100 | 6 | +32 | 128,000 | 10,395,600 | 12 |
| 6★ | 9,680,600 | 8 | +38 | 152,000 | 20,076,200 | 20 |
| 7★ | 16,149,800 | 16 | +46 | 176,000 | 36,226,000 | 36 |
| 8★ | 22,260,700 | 21 | +56 | 208,000 | 58,486,700 | 57 |
To fully upgrade one plugin from 0★ to 8★, you'll need a grand total of 58,486,700 EXP, 57 identical copies, and 20 catalysts. If a plugin is already at 6★, the journey to 8★ will require an additional 38,410,500 EXP and 37 copies. The cost increasingly shifts towards duplicates, with 7★ and 8★ alone demanding 16 and 21 copies, respectively.
Beyond 8★: The Path to 9★ and 10★
The 9★ progression follows the same eight-marker structure as 5★–8★. The first two EXP markers for 9★ cost 5,777,000 and 5,892,500 EXP (totaling 11,669,500). Each marker at 9★ grants an additional +64 to the primary hero stat and 29,000 power. Secondary stat increases per marker are +1.5% Troop ATK or DEF, +0.6% Troop DMG, or +0.3% Troop HP.
Growth rate projections estimate the full 9★ EXP cost to be approximately 30.7 million, and 10★ around 42.3 million. This translates to cumulative EXP from 0★ of roughly 89.2 million for 9★ and 131.5 million for 10★. These figures are current estimates, not confirmed total upgrade costs, as the remaining EXP markers and exact-copy gate requirements for 9★–10★ are currently unknown. Do not rely on these projections for your final material budget.
Crafting Exact Copies
The Craft tab, found alongside your Backpack, features a dedicated faction section. Here, you'll find four purple Mk III and four orange Ultra IV recipes for each faction. Each recipe requires 100 materials of its corresponding rarity.
| Item to Craft | Materials Required |
|---|---|
| 1 purple plugin | 100 purple Plugin Crafting Materials |
| 1 orange plugin | 100 gold Plugin Crafting Materials |
If all 57 duplicates needed for 8★ must be crafted, this would cost 5,700 gold materials. Crafting the initial plugin adds another 100. While copies from choice boxes or random drops can reduce this cost, only an identical orange plugin can satisfy a duplicate gate requirement.
Plugin Chests: Targeted Copies and Orange Odds
An Orange Plugin Choice Box allows you to select one of the 12 available orange plugins. A random orange result will draw from all 12 options; therefore, a specific plugin has a 1-in-12 chance. With three factions, only 1 in 3 random orange results will belong to your desired faction. Chest pity mechanics ensure an orange plugin after a certain number of misses.
| Chest | Orange Chance Progression | Guaranteed By | Approx. Opens Per Orange |
|---|---|---|---|
| Orange Choice Box | Pick one exact plugin | Every box | 1 |
| Random Orange (gold) | 20.19% on first open; approx. +20.18 points after each miss | Open 5 | ~2.5 |
| Purple | 0.01% early; rises approx. 1.474 points per miss from open 11 | Open 78 | ~26 |
| Blue | 0.01% early; rises approx. 0.0824 points per miss from open 41 | Open 500 | ~85 |
| Green | 0.01% through open 100; then rises approx. 0.00098 points per miss | Open 1,000 | ~500 |
Upon a non-orange result, a gold chest grants 20 gold crafting materials. A purple chest can yield one purple plugin (78.9%), two purple plugins (10.5%), or two gold materials (10.5%). A blue chest typically provides one blue plugin (71.9%), one purple plugin (20.2%), or one gold material (7.9%). A green chest offers one green plugin (60.1%), one blue plugin (30.1%), one purple plugin (4.8%), one purple material (3.8%), or one gold material (1.2%); percentages are rounded.
For fulfilling exact-copy gates, prioritize the Choice Box over a random orange chest. Purple, blue, and green chests primarily serve as sources of EXP fodder and crafting materials, with orange drops being an added bonus.
Plugin Resonance: Synchronized Slot Leveling
Activating Plugin Resonance requires four installed orange plugins. The resonance level is determined by the lowest star level among the installed plugins. For instance, one 5★ plugin alongside three 3★ plugins will result in 3★ resonance. While a higher-starred plugin still enhances its own stats and skills, advancing the lowest slot is key to improving the shared resonance bonus.
| Lowest Plugin Star | All Heroes' ATK and DEF, Each |
|---|---|
| 0★ | +20 |
| 1★ | +40 |
| 2★ | +60 |
| 3★ | +80 |
| 4★ | +100 |
| 5★ | +150 |
| 6★ | +200 |
| 7★ | +250 |
| 8★ | +300 |
| 9★ | +350 |
| 10★ | +400 |
To upgrade all four orange plugins from 0★ to 8★ simultaneously, you'll need 233,946,800 EXP, 228 identical duplicates, and 80 catalysts. Achieving the 9★ resonance tier demands that every installed Tactical Plugin be an orange quality plugin at 9★.
Plugin Reset: Reallocating Resources
Uninstalling a plugin is a free action. The Plugin Reset function, available after uninstallation, fully refunds invested star-up EXP, exact duplicates, and catalysts. Green, blue, or purple plugins that were previously used for EXP are returned as the equivalent amount of EXP, not as the original items. This feature allows players to reallocate their star-up investments to a different orange plugin without loss.
Quick Tips
- Match Faction: Always equip plugins that match your vehicle's faction for optimal performance.
- Prioritize Resonance: Level all four orange plugins evenly to maximize the shared resonance bonus.
- Save Duplicates: Keep exact orange plugin copies for material gates; they are critical for star-ups.
- Strategic Crafting: Use gold crafting materials to target specific orange duplicates needed for upgrades.
- Choice Box Value: Use Orange Plugin Choice Boxes for specific duplicates, as random chests are less reliable for targeted upgrades.
- Reset for Efficiency: Don't hesitate to use Plugin Reset to reallocate resources if your strategy changes.
