How to Run Metal Arms

Introduction

If you are speedrunning this game, please introduce yourself in this thread.

Setup

Because the introductory cutscene is quite long, the best way to run this game is to create a profile, complete the first level, then just copy that profile to a different memory card every time you want to start a new run. This will let you skip the first cutscene, and even though it will save the coring charge and washer count of the copied profile for the start of level 2, those shouldn't be changing anyways on normal runs.

Timing

For single-segment runs, it is handy to keep a save file that has the first level completed, so that any time you start a new run you can simply copy that file and replay level 1, which will let you skip the intro cutscene. The only thing to be wary of is that you should always finish the level with the same amount of coring charges: the typical any% run should finish with 4 charges, while the 100% run should finish with 9.

Splits should be marked the instant you are able to continue past the stats screen at the end of a level; mostly because it's easier to hit the shortcut key there instead of when the save window comes up.

For segmented runs, the time starts the first frame that you can see the player, and ends on the first frame(inclusive) that you can see the "Saving Profile" notification.

Note: In-game times are only accurate on two conditions: You don't die, and you don't reset. Dying sets the timer back to what it was at the last checkpoint, and resetting doesn't reset the timer.

Version Differences

While there are no significant differences from GC, PS2, or XBOX. Certain areas may be less laggy as well as loading time differences. This needs testing

Continuity

While the game is separated into levels, you bring the state of every weapon and ammo count with you. The only thing that changes between levels is that your health is refilled.

When a level is finished for the first time, the game records the state of your gun and ammo and loads it into the next level. Replaying a level does not affect the state of your weapons for the next level.

Cutscenes

This game only allows you to skip pre-rendered cutscenes if you are replaying a level. In-engine cutscenes can be skipped at any time though.

Checkpoints

If you die after a checkpoint, the game will restore you to either the health you had when you hit the checkpoint, or 1.5 bars, whichever is higher. This can be abused to gain health and continue on a mission without going out of the way for health drops.

Reloading the game to a previous checkpoint does strange things to the game also. Enemy units are reset to their original positions, but their AI is left on the state that it was at when you died. This means that enemies who were alert to your presence before dying will still be alert after you reload the checkpoint, and are likely to behave differently as a result.

Authors note: as an example, in Into The Trenches a Titan that I would usually be able to sneak behind on the first run through, would instantly turn and shoot at me on the next run through.

These points hold true for resetting the level as well.

Item Drops

All enemy units have specific items that they drop upon death. This includes washers, ammo, and health pickups. Learning which enemies drop which items is absolutely necessary for efficiently completing runs.

Glitches/Techniques

Used

Cutscene Physics

Cutscenes work a bit differently in this game than in many others. All cutscenes besides the intro and exit of the game itself are done in-engine in real time. This means that physics will still apply to objects that aren't being directly controlled by the cutscene. This can be used to move Glitch while the cutscene is playing: for example in Do Ore Die, there is a brief gap between when you hit a button and when a scene plays that gives you just enough time to jump off a platform; while the scene plays out, Glitch keeps moving to the bottom of the room, and this saves a couple seconds on the run time.

Ramp Jump

You can jump much higher if you jump right after hitting a slope.

Wrench Clipping

When moving towards a wall, use the wrench right as you hit and you will clip through when you rebuild.

Speed Sliding

When you are pushed above a certain speed, the physics change slightly and you slide across the ground. This can be done either by going down a steep slope, landing and moving forward on a slope after jumping, or being pushed into it from various vehicles or NPCs in the game (i.e. the loader, or zombiebots).

Tank Climbing

You can use a tank to access heights that are not normally reachable. This is most commonly done by grinding a tank against a wall and getting out to jump off the tip before it slides back down.

Scope Loading

While Out of Bounds, the game will sometimes load too many areas, resulting in a reset back to your last checkpoint. This can be prevented by using your scope when crossing these areas.

Unused

Pentagonal Box Glitch

In the Morbot region, there are often pentagonal shaped boxes that act as elevators. Getting on top of one while the box is traveling upwards can result in random effects. Sometimes you will be warped randomly throughout the map without any control of where you land, and other times you may be pushed out of bounds. Using this glitch in the level 'I, Predator' lets you get on top of the building you start in, and easily get out of bounds. It is even possible to drop down to the large tunnel areas (Were you are supposed to be in a predator)and destroy the generator as Glitch. Unfortunately, this is useless because there is no way to get out afterwards. It is also useless to travel out of bounds throughout most of the map because there are many walls blocking the way.

Titan Clipping

This can only be done in Multiplayer. Have one person get in a tank and the other get in a titan. a few corners in certain maps will actually allow a titan to be clipped out by a tank pushing them. This will not work the same way in Solo mode since there are very few places were this would be useful. Also note that Mils in Tanks can not push you like a player can.

Theories

Tether Clipping

Since Tethering gives the same animation as using the wrench, it was thought to be possible to clip OoB with a tether as well. This does not work, unfortunately, since you need to be facing the wall from the front rather than the back.

Tether Voiding

It is possible to fall off a ledge while falling apart from tethering. This was thought to be able to get underneath water or passed death zones. Instead, you only fall a certain distance and you will still die from water and death zones.

Keep the wrench

If it was ever possible to keep the wrench for later levels. The game would most likely be considered broken. There is no lead on how to even began with this, however.

Enemies

General Notes

Aside from bosses, the only damage that truly counts towards a kill is damage that directly hits the main body of the enemy unit. Damage to the head, arms, legs, or rocket launcher (in the case of Titans) only affect how those enemies react/move.

Grunt

Can be killed with:

• 20 SPEW Rounds
• 1 direct rocket hit
• 2 indirect rocket hits
• 2 Scatter Blaster hits

Elite Grunt

Can be killed with:

• 4(?) Explosive devices (rockets or grenades)
