Jake normally has several unique weapons to use - the Nailgun, the Bottle, the Acid Vial, and the Nunchucks (as Dallas). However, there is an extra weapon that goes unused for him. In the game's code and sprite sheets, he can use a single MP5, as opposed to The Son and Mark's dual MP5s. It functions like the Uzi, only with 32 rounds and the pistol's gunfire sound.

There's no "normal" way to spawn a single MP5 in the Level Editor. The weapon spawn list does not feature it, and Mafia enemies do not carry it. Even modding a level so Jake can fight the MP5-wielding Heavy Soldiers will only leave an Uzi for him to use.

There are 2 ways to add it: using Notepad++ or using the Cutscene Editor's NPCs. This section will cover the NPC method.

To start, create a blank level and play with the Jake or Irvin masks. Next, go to "Create Cutscene" and place down a CobraWalkMP5 sprite that is killable. Place a melee weapon down by your character. Add some enemies if you want to test it out.



Then, with whatever weapon you have on hand, hit the cutscene sprite. He will drop an MP5.



Now you have a machine gun! Pick it up and use it like any other weapon!



This method also works for other player and enemy weapons, so long as the NPC carrying it is killable.

If you want to add the MP5 or other unavailable weapons more subtly, here's how to add it by itself with Notepad++!

For whatever Jake level you're making, add an Uzi somewhere on the level. Then, pull up that floor's .obj file and search for sprite 303. As long as there are no others on the map, there should be a 303, and two lines below it there should be a 178.

Replace the 303 with 1459 and the 178 with 882. Load up your map again, and an MP5 should be there in place of the Uzi. Save the game on that floor to make the change permanent.

To ensure that your desired weapon spawns, it is best to replace a normal item (like AcidBath1 or TigerFur) with the weapon's IDs. This gets around restrictions on what weapons can spawn for characters. This means you'll be able to add them no matter who you are playing as.

Keep in mind that not all characters can use all weapons, though. Also, any weapon that replaces a normal item will not float or be highlighted when you are near it in Editor view (it will appear normally in-game, though.)

Bold weapons cannot be picked up by any character - doing so just removes them from the floor. Underlined weapons can be picked up and used, but only by 1 character.

RIchter has a unique perk when using the Axe - he can destroy breakable walls when swinging it. This does not happen when playing as Jacket or LSD Son (the special version of The Son used in Apocalypse).



No other character in HLM2 can use the single MP5. Jacket could in the first game, but this ability does not carry over in the sequel. Mark and The Son can dual-wield MP5s, but trying to pick up new ones just removes them from the floor.

Thanks for reading! Have fun giving Jake the power of German engineering!
