MSA Build Up

Build Up in Metal Slug Attack is the equivalent of Metal Slug Defense's Customise menu. Here a player can upgrade their Base and Units as well as setting up their decks for a fight.

Customize Unit

Build Up Unit

This menu is dedicated to improving individual Units' Stats. There is a good number of ways of doing so, each with their own requirements and benefits. In this menu units are sorted by several criteria (cannot be changed, but can be filtered by faction):

  • Ownership status (whether the player has it unlocked).
  • Level.
  • Number of skills unlocked ("released").
  • Evolution tier.

Evolution

MSA Example Evolve

Units can use up corresponding parts to Evolve to the next tier (represented by the frame around a unit's icon: Iron -> Bronze -> Silver -> Gold -> Platinum). Every time a new tier is reached base HP and Attack Damage are multiplied by 1.1 (see the table below), additionally the AP cost is reduced by a constant value (for that unit).

Tier Parts
Required
Total Base HP
and Attack Damage
I Iron 10 (10) 1.0 (1.10)
II Bronze 20 (30) 1.1 (1.11)
III Silver 50 (80) 1.21 (1.12)
IV Gold 100 (180) 1.33 (1.13)
V Platinum 150 (330) 1.46 (1.14)

Aside from HP and Attack Damage, some units' Resistance is affected by Evolution:

  • Marco (+3)
  • Tarma (+4)
  • Eri (+2)
  • Fio (+2)
  • SV-Camel

A unit starts evolved to a specific tier (stat bonuses included, except AP cost reduction for most units) depending on its Rarity (the number of parts needed to unlock it):

Rarity MSA rarity Normal MSA rarity Rare MSA rarity Super Rare
Parts
Required
MSA Unit Part (Single) 10 MSA Unit Part (Single) 30 MSA Unit Part (Single) 80
Starting
Tier
I - Iron II - Bronze III - Silver
MSA unit --- I-stock MSA unit --- II-stock MSA unit --- III-stock

Some of rare units do have their AP costs decreased when unlocked - the initial cost listed in the units' card goes down immediately:

  • Ring Laser Mecha - from 130 to 123.
  • Ohumein-Conga's (Red) - from 210 to 200.

Equipment

MSA Example Skills Unlocked

Boot Items can be put into Equipment Slots (cannot be unequipped) for a permanent stat increase that is affected by Skills unlocked and levels of the latter. Items required differ greatly among units, as do corresponding effects. After filling out all 6 equipment slots a skill can be unlocked (MSA Skill small + Released as the game puts it), providing either special attacks, effects, or a stat increase. Effects from items required by previous skills remain and stack with each new set. The amount of skills unlocked is represented by stars under a unit's icon.

Skills

Skills are the power-up enhancers of every units the game. Unlike Metal Slug Defense's level up. Skills can be found in the units tab on the right side.
MSA Skill big

Skills in turn can be upgraded for MSD currency MSP MSP via Skill Strengthening (Called "List of Skills" pre-1.6.0) (not higher than the unit's current MSA Player Level Level past Level 10) and provide with a marginal increase in effectiveness. Costs of each level linearly increase depending on which skill it is:

  • Skill 1 - MSD currency MSP 500.
  • Skill 2 - MSD currency MSP 1,000.
  • Skill 3 - MSD currency MSP 3,000.
  • Skill 4 - MSD currency MSP 5,000.

Levelling Up

MSA Example Unit Level

MSP can be spent on Powering-Up that increases a unit's Level by 1 (represented by the number under a unit's icon, and not higher than the player's current Level past Level 10) and increases HP and Attack Damage by a constant fraction of the original value, every 10th upgrade adding the double of that fraction:

With most units, every 10 levels increase HP and Attack Damage by 50%, however there are exceptions:

  • R-Shobu Ver. P.M. - additional 100% of Short (Near) Attack Damage.
  • Sasquatch - additional 25% Resistance.
  • Nop-03 Sarubia additional Resistance(+1) for each level.
== Customize Deck ==
Build Up Deck

Players are given 3 decks to organise battle groups with. Up to 10 units can be in one deck at a time, plus a unit for hire (for MSP) provided by one of the Guild members (if the player is in a guild) that is selected before a mission. If a deck if made with units exclusively from a single faction, they all receive a +10% HP bonus.

More decks can be bought with medals; this is typically not recommended as the medals can be used for other purposes.

Customize Bases

Players can upgrade various stats that affect their effectiveness as a whole, regardless of deck composition. Every upgrade thread cannot exceed the player's Level (past Level 10) and costs progressively more to move up.


Build Up Background

Sortie Level

Base Sortie Level

Increases Sortie Point storage capacity by 2 with every upgrade (stacks with capacity bonus from the player's Level). Useful for players that cannot spend accumulating SPs in time before they exceed storage capacity.

Base Level

Build Up Base

Increases the base's Health Points. It starts with 3,000 HP at level 1 and each upgrade adds up 500 HP. A somewhat important upgrade.

13,000
23,500

Development Speed Level

Base Development Speed Level

Increases speed at which the player generates APs in combat. It is an extremely important upgrade when battling, as it will increase the speed of how fast your base will generate AP, which in turn will determine how fast you can deploy units. The player starts at normal AP production speed (based on their AP production level). There are 12 upgrades, with each upgrade increasing your AP production by 50%, which stacks up to 600% of your AP production level.

Hangar Level

Base Hangar Level

Increases how many APs the player can store while in combat. The player starts off with an initial limit which is based on how developed their Hangar Level is. This also stacks with the AP production upgrade in a battle, so the higher your hangar level is, the more AP you can store at any given time. Each on-site upgrade increases the max amount of APs you can hold at any given time by 50% of your Hangar Level. There are 12 of these upgrades, at that level, players can store up to 600% of what their Hangar Level can hold at level 1. Prior to the 1.6.0 patch, the maximum amount of AP that could be stored was 9,999.

Production Speed Level

Base Production Speed Level

Fairly important in battles, as increased production levels means a unit can be quickly redeployed again after being sent out to battle.

Destruction Bonus Level

Base Destruction Bonus Level

Increases the amount of AP that is gained when killing enemy units. Important in prolonged battles.

MSP Gain Level

Base MSP Gain Level

Improves MSP rewards gained from completing missions. It starts with a multiplier of 1.0 at level 1 and each upgrade increases the multiplier by 0.1. MSP rewards determined by completion rank (how fast a level is beaten) are not affected.

Metal Slug Attack Level

Base Metal Slug Attack Level

Increases strength of the charging self-destructing SV-001 command power. [Super Metal Slug Attack x3 effect to be reflected.]

It is rarely used by high level players, as it provides very little effects for them. Apart from dealing very little damage (though it can kill low health units with ease), it is also capable of knocking back any unit it hits if they are not killed by it.

Metal Slug Charge Level

Base Metal Slug Charge Level

Speeds up recharge of the said command power.

Recovery Charge Level

Base Recovery Charge Level

Speeds up recharge of recovery. When activated, it will heal all units back to 100% health, and allows the player to immediately redeploy the same units again without waiting for cooldown. Often used with powerful units to overwhelm the enemy.
