History VideoGame / MetalSlugDefense

* BoringButPractical: The Rebel Rifleman has a bit less HP than the basic soldier, but is still cheap at 60 AP and shoots from afar while protected by other units. The Bikers cost 90 AP but have an above-average 1000 HP at level 20 and move faster, while otherwise acting just like the riflemen.

* ExcusePlot

* GlassCannon: The HP of the player's base isn't such an important stat to upgrade because if a decent group of units reaches a base at all, it will most likely be done for because defending units won't be able to either charge their special moves to do anything or even cover the base's hitbox.

* NostalgiaLevel: All arenas are taken from the series' levels.

* TurnsRed: Subverted by the Iron Nokana. It is supposed to lift itself and reveal a flamethrower when low on HP, but here it lifs itself and immediately explodes.

* ZergRush: The descriptions for the basic Soldier and the Rebel Infantry advise this strategy, as they cost only 30 AP and have little delay between uses. They're too fragile to be any good fighting with their knives, but peharps a shower of their granades could bring good results?

* ActionBomb: The Zombie Rebel Soldier and the Mutated Soldier self-destruct upon reaching a target. The player can also release an explosive SV 001 once its meter is filled.

* {{Cap}}: The level cap for units and the player base's attributes is 10, but it expands to 20 once the second loop is unlocked.

* AwesomeButImpractical: Zombie Marco has a fine 3600 HP at level 20 and costs less AP than most tanks, but has as much delay between uses as them, his normal attack is less effective than normal Marco's and the thing you'd want him for, the very powerful and long-ranged blood jet vomit, takes a large amount of time to charge. And if anything knocks him down he takes too long to stand up while still getting hit.

* TheCameo: Every heroic character from the series is at least mentioned in the game, even those from the ''R'' and ''Advance'' spinoffs or the Ikari Warriors. The villain side doesn't get such attention, though. The evil guys from ''4'' and beyond don't appear in the game.

* GlassCannon: The HP of the player's base isn't such an important stat to upgrade because if a decent group of units reaches a base at all, it will most likely be done for.

* RandomlyDrops: Upgrades are unlocked upon rescuing sets of prisoners, but the prisoners aren't seen in the levels and seem to be saved at random upon finishing a mission, [[FakeLongevity to force replays.]] It's especially annoying in regards to [[ThatOneLevel the harder missions]] and the bonus ones that are only available for a short time on each day. Of course, you can use [[BribingYourWayToVictory silver medals]] to buy items that guarantee that one prisoner will appear.

* LimitBreak: A [[ActionBomb self-destructing SV 001]] can be sent when its meter fills. It insta-kills all small enemies and explodes upon colliding with a larger enemy or the opposing base. This is important when fighting Jupiter King, which [[InstantDeathRadius makes such a mess]] out of anything you send at it that, at least early on, you're forced to just buy time and try to get rid of large enemies until the bombastic SV 001 is available for damaging and pushing King away.

* AdvancingBossOfDoom: Every enemy is moving towards the player's base, after all. Even ones such as Jupiter King, who originally moved away. The Huge Hermit deserves special mention for being the only enemy on its mission.

* BoringButPractical: The Rebel Rifleman has a bit less HP than the basic soldier, but is still cheap at 60 AP and shoots from afar while protected by other units. The Bikers cost 90 AP but have an above-average 1000 HP at level 20 and move faster, while otherwise acting just as the riflemen.

* DefeatMeansPlayable: Clearing a set of levels usually means unlocking the enemies featured in them... [[DoubleUnlock to be bought at the shop.]]

* EverythingsDeaderWithZombies: The zombie enemies from ''Metal Slug 3'' are present. This includes Zombie Marco.

* BigBad: Morden actually fights on an alien tank without being betrayed this time. [[BiggerBad The Mars People]] are featured with more focus in the last set of bonus levels.

* BoringButPractical: The Rebel Rifleman has a bit less HP than the basic soldier, but is still cheap at 60 AP and shoots from afar while protected by other units. The Bikers cost 90 AP but have an above-average 1000 HP and move faster, while otherwise acting just as the riflemen.

* AscendedExtra: Sandbags, usually used by granede-wielders of the Rebel Army to annoy players, are an essential tool for survival in this game.

* BigBad: Morden actually fights on an alien tank without being betrayed this time.

* BossBattle: You'll encounter a few of the huge bosses from the series over the course of the game.

* {{Cap}}: The level cap for units and the player base is 10, but it expands to 20 once the second loop is unlocked.

* TheGoomba: The basic blue soldier you start with. Cheap and with 300 HP at level 10. He attacks with a knife and can throw granades. The green normal rebel soldier is an unlockable and he seems to have the same stats and attacks as the blue one.
* HumongousMecha: [[http://metalslug.wikia.com/wiki/Jupiter_King Jupiter King]] from ''Metal Slug 3'' appears in area 10, stage 4. The Mars Mecha is also present.

* LuckBasedMission: Upgrades are unlocked upon rescuing sets of prisoners, but the prisoners aren't seen in the levels and seem to be saved at random upon finishing a mission, [[FakeLongevity to force replays.]] It's especially annoying in regards to [[ThatOneLevel the harder missions.]] Of course, you can use [[BribingYourWayToVictory the secondary currency]] to buy items that guarantee that one prisoner will appear.

* BonusDungeon: Every few hours, a harder set of missions becomes available for a while.

* TimedMission: The fight against Tetsuyuki has this sense of urgengy, due to the boss being able to use a laser that hits the entire field. Multiplayer battles have a 99 seconds time limit.

* [[spoiler: AWinnerIsYou: The game reuses the ending scene form ''Metal Slug 3'', while talking about how the heroes will continue to battle any evildoers.]]

* BigfootSasquatchAndYeti: The Sasquatch is one of the better close-range characters due to his high power and HP.

* HumongousMecha: [[http://metalslug.wikia.com/wiki/Jupiter_King Jupiter King]] from ''Metal Slug 3'' appears in area 10, stage 4.

* AdvancingBossOfDoom: Every enemy is moving towards the player, after all. Even ones such as Jupiter King, who originally moved away from the player. The Huge Hermit deserves special mention for being the only enemy on its mission.

* ChargedAttack: Each unit can use a special move by spending a meter that fills over time.

* LimitBreak: A [[ActionBomb self-destructing tank]] can be sent when its meter fills. It insta-kills all small enemies and explodes upon colliding with a larger enemy or the opposing base. This is important when fighting Jupiter King, which [[InstantDeathRadius makes such a mess]] out of anything you send at it that, at least early on, you're forced to just buy time and try to get rid of large enemies until the bomb tank is available for hitting the boss.

* {{Mecha}}: The LV Armor and the Slug Gunner.
* OhCrap: If a sandbag man gets hit before setting a barrier, he freaks out and flees. Madoka is also shown panicking in her icon if a mission is lost.

''Metal Slug Defense'' is a mobile game released from out of nowhere by SNK in 2014. As made apparent by the title, it is a TowerDefense game set on the ''VideoGame/MetalSlug'' universe. Players spend a constantly filling meter on characters of varying properties, which then march foward in hopes of overwhelming and destroying the opposite base. The various human, monster and machine units have unique charged moves to be used wisely. The game can be played online with friends or random people, but one should first prepare before encountering players on a far stronger level than themselves.

* AdvancingBossOfDoom: Every enemy is moving towards the player, after all, but enemies such as the Huge Hermit deserve special mention, as they already were this in the main series.
* AnnouncerChatter: The usual anouncer does his thing when the main characters use their special attack, such as Marco using the HEAVY MACHINE GUN or Fio using the ROCKET LAUNCHER, for example.
* AttackAttackAttack: All characters will advance foward and exchange fire with enemies until being killed.

* ExtendedGameplay: Clearing the game once unlocks a harder loop. It is more of the same in the old arenas with leveled-up enemies, but some missions do surprise the player with an out-of-place boss such as Allen.

* TheGoomba: The basic blue soldier you start with. Cheap and with 300 HP at level 10. He attacks with a knife and can throw granades. The green normal rebel soldier is an unlockable and it seems to have the same stats and attacks as the blue one.

* LimitBreak: A [[ActionBomb self-destructing tank]] can be sent when its meter fills. It insta-kills all small enemies and explodes upon colliding with a larger enemy or the opposing base. There's at least one boss that [[InstantDeathRadius makes such a mess]] out of anything you send at it that you're forced to just buy time and try to get rid of large enemies until the bomb tank is available for hitting the boss.

* OhCrap: If a sandbag man gets hit before setting a barrier, he freaks out and flees.

* TimedMission: The first boss fight has this sense of urgengy, due to the boss being able to use a laser that hits the entire field.

* AdvancingBossOfDoom: Every enemy is moving towards the player, after all. The Huge Hermit, which was this trope in ''Metal Slug 3'', even is the only enemy in its level, to intimidating effect as it takes out the bridge the battle is taking place on.
* AnnouncerChatter: The usual anouncer does his thing when the main characters use their special attack. Marco using the HEAVY MACHINE GUN, for example.

* BribingYourWayToVictory: The secondary currency can be used to buy items that grant advantages in the missions.

* ExtendedGameplay: Clearing the game once unlocks a harder loop.

* LimitBreak: A [[ActionBomb self-destructing tank]] can be sent when its meter fills. It insta-kills all small enemies and explodes upon colliding with a larger enemy or the opposing base. There's at least one boss that [[InstantDeathRadius makes such a mess]] out of anything you send at it that you're forced to just buy time and get rid of enemy tanks until the bomb tank is available for hitting the boss.

* TankGoodness: Many tanks from the series are available here.

* BonusDungeon: Every few hours, a harder set of missions becomes available for a while.

* TheCameo: Every heroic character from the series is mentioned in the game, even those from the ''R'' and ''Advance'' spinoffs or the Ikari Warriors.
* {{Cap}}: The level cap for units and the player base is 10, but it expands once the second loop is unlocked.

* EverythingsDeaderWithZombies: The zombie enemies from ''Metal Slug 3'' are present, including Zombie Marco.

It is a free-to-play game and, as to be expected, there are elements such as layers of level grinding, missions costing credits that recharge over time and most of the unlockable characters only being available through a secondary currency more accessible for those willing to spend money on it.

* AdvancingBossOfDoom: Every enemy is moving towards the player, after all. The Huge Hermit, which was this trope in ''Metal Slug 3'', even is the only enemy in its level, to intimidating effect as it takes out the bridge the battle is taking place on.
