ISMC 2 Early Access Release 2: Unlimited Gunstruction

Release Notes

Project Arbusto is an expanded and fully reworked version of the ISMC mod made for my personal server that brings new theaters with full PvP and PvE support, an expanded weapons customization system, weapons and attachments to Insurgency Sandstorm. The mod has finally left the Technical Preview phase and is ready for public use, now that the core weapons systems have been fully re-done. This early access version shows the first iteration of the expanded gunsmith system for Insurgency Sandstorm. All NWI weapons have been re-built and remastered to fit the new gunsmith system, and now all share a common universal pool for optics, siderail, underbarrel (with exceptions for weapons with no foregrip animations), and muzzle. In addition, most ISMC guns have been converted to the new gunsmith system,  many weapons have been converted to gunsmith variants of base NWI weapons to avoid having a million functional duplicates of the same gun.

There are some new cosmetic theaters with unique characters and fire support based around the theme of modern military combat. For those who prefer the stock NWI characters a legacy theater is provided. 

Cost balancing adjustments have been done to weapons and attachments. The most expensive weapon costs 6 supply and the most expensive attachment costs 4. The game is now very playable with 15 supply, but for a fun experience 25-30 supply will let you fully kit out your weapons without feeling too OP.

Feature List:

  • Full PvP and PvE support.
  • New gunsmith system for all NWI and ISMC weapons with barrel lengths/stocks/handguard options for many gun platforms.
  • Modern military theme theaters with custom cosmetics and fire support for a change in experience.
  • Legacy theater support with NWI characters and fire support. 
  • Modular modding support. Independent expansion packs (i.e. vehicles, factions) are planned to allow server owners to load only the content they want.
  • Modular gameplay modification mutators (they will also work with mods like Star Wars and Sandstorm 1944) to customize further aspects of the game.

Installation Instructions

In order to play Project Arbusto you just need to load one of the 8 different theaters in this release:

Main Theaters (No gun handling training upgrades)

  • ISMCGunfighter: Based on the FullyLoaded loadout, everyone has access to all guns, no fire support.
  • ISMCGunfighter_Tac: Based on the FullyLoaded loadout, everyone has access to all guns, adds a team leader class to enable fire support. Similar to regular ISMC
  • ISMCGunfighter_Legacy: Based on the FullyLoaded loadout, everyone has access to all guns, no fire support. Regular NWI cosmetics.
  • ISMCGunfighter_Tac_Legacy: Based on the FullyLoaded loadout, everyone has access to all guns, adds a team leader class to enable fire support. Similar to regular ISMC. Regular NWI cosmetics.

In addition we offer casual theaters that add weapon handling training upgrades to make the game feel a bit faster on reloads and draw times, the upgrades cost zero supply so everyone can use them without it being a disadvantage.

NOTE TO SERVER OWNERS: Casual theaters are now deprecated. Loading a casual theater will not work.

Optional: Gameplay Modifier Mutators

If you want to switch up the gameplay a bit there are 12 different mutators to modify gameplay. Just add a combination of movement, health or both for a different gameplay experience.

Movement Mutators:

  • TacticalMovement: Slower movement (85%) with regular animations
  • TacticalMovementHC: Slower movement(85%) with hardcore animations.
  • CasualMovement: Faster movement (110%) with regular animations.
  • CasualMovementHC: Faster movement (110%) with hardcore animations.
  • OldSchoolMovement: Faster movement (110% movement, 115% sprint) with no free aim.
  • 90sMovement: Faster movement (110% movement, 115% sprint) with no free aim and no ADS.
  • ModernMovement: Faster movement (110% movement, 115% sprint) with free aim.
  • HCMovement: Regular movement with hardcore animations.
  • CasualMovementMW: Faster sprint and slide (120%) with regular movement speed and animations.

Health and Damage Mutators

  • TacticalHealth: 80% Health with +20% headshot damage
  • CasualHealth: 133% Health with -30% headshot damage.
  • OldSchoolHealth: 200% Health with no changes to headshot damage.

 

Optional Gamemode Modifier Mutators:

There are also gamemode modifiers that can switch up gameplay a bit in this game. These mutators work so far in both PvP and Co-Op. The changes are not drastic and should work with all maps (tested only on NWI and the INS2014 pack).

Right now there is only one modifier, but I will add more as they get tested and developed.

Gamemode Mutators:

  • AdvancedObjectives: Adds randomized items (Mounted MGs and ammo crates) to every objective in a map, emplacements get reset on every round. The parameters for spawning can be configured in Game.ini
  • SuppliedObjectives: Adds supply crates to every objective in a map, emplacements get reset on every round. The parameters for spawning can be configured in Game.ini
  • DisableFS: Disables fire support entirely.
