Half Life 2 Mobility Mod adds Titanfall-inspired wall running mechanics to Valve’s shooter

11 Comments

Modder ‘Rob’ has released a brand new version of his Mobility Mod for Half-Life 2. This mod basically enhances overall mobility in Half-Life 2 by adding – among other things – the wall running mechanics players experienced in the Titanfall games.

Mobility Mod Version 2 is based on the Episode 2 Engine and combines Half-Life 2, Episode 1, and Episode 2 into one mod (just keep scrolling on the chapter menu to get to the episodes). Moreover, this new version comes with new melee controls, a very basic tutorial for the new melee, new HUD features and some movement enhancements.

In short, and while the control mechanics are different from the vanilla ones, this mod will allow you to re-experience Valve’s classic shooter in a completely different way.

Those interested can download the mod from here, and below you can find its complete changelog.

Half Life 2 Mobility Mod Version 2 Release Notes

New Features

  • Based on the Episode 2 Engine
  • Combines Half-Life 2, Episode 1, and Episode 2 into one mod (just keep scrolling on the chapter menu to get to the episodes)
  • New melee controls:
    • melee key for a quick crowbar attack
    • hold melee key and press secondary attack for a crowbar slash attack, which hits multiple targets and does more damage, but is slower
    • hold melee key and press primary attack for a rocket-boosted surge attack, which pushes you forward, hits as soon as the target is in range, and does a lot of damage.
    • Surge attack while in the air lets you fly a short time, or change direction. Surge attack while crouching will trigger a slide even if you weren’t moving.
  • Very basic tutorial for the new melee
  • The airboat rockets seemed to please the personnel last time, so now there’s a portable version. It’s called the EGAR (Everyone Gets A Rocket!), and you can get it by typing give weapon_egar in the console.
    • Like the airboat rockets, it regenerates ammo.
    • Hold secondary attack to target enemies, and release to fire rockets.
    • Press reload to lock all remaining rockets onto the last target.
    • Unlike the airboat rockets, press primary attack to target whatever is under the cursor, even if it’s just a spot on the ground.
    • A nice side-effect of this system is that if you hit primary and secondary attack at the same time, it fires one rocket at whatever you’re looking at, so it’s like a quake-style rocket launcher.
  • Movement enhancements:
    • Time-to-duck has been reduced, so sliding is much more responsive.
    • Console variable to lock direction while sliding, so you only slide in a straight line, no matter which way you’re facing (set sv_slide_lock to 1)
    • Console variable to limit sliding, slide-jumping and wall-jumping to only boost you to sv_maxspeed. Normally these speed boosts are cumulative and not limited (set certain_restrictions to 1. I recommend this setting. It makes the game feel less crazy, and more consistent.)
  • lessclip – it’s like noclip for invisible walls. Use with caution, because it turns out there are a lot of invisible walls and ramps that you need.
  • New HUD features:
    • artificial horizon (can be turned off or set to a custom opacity with cl_horizon console variable)
    • crosshair hit markers (diagonal lines. Can be turned off, set to a custom opacity with cl_hitmarkers, made bigger or smaller with cl_hitmarks_scale, faster or slower with cl_hitmarks_fadetime)
    • shotgun hit markers (circles showing hit pattern. Can be turned off or set to a custom opacity with cl_shotgun_hitmarks, can change the size of the circle with cl_shotgun_hitmarksize, can change the size of the pattern with cl_shotgun_hitmarkspread)
    • New grenade count display. In v1 there was a big row of grenade icons along the bottom, but that would clash with the vehicle locator display in ep2, plus it was a bit ugly.
  • Destroying an APC ejects the driver up into the air.
  • Unlocked a door in Nova Prospekt so that you can skip the first conversation between Alyx and Eli.
  • ‘CONTINUE LAST SAVE’ button on main menu – loads your last autosave.

Returning from version 1:

  • Wall-running
  • Double-jumping
  • Power-sliding
  • Ledge-climbing
  • Grenade button, ability to cook grenades
  • Unlocked Field-of-View (In HL2 the max was 90)
  • Tutorial and mini-campaign (only a tiny change from version 1, so if you played through it already, you’re not missing anything if you skip it)
  • Reduced bullet spread of automatic weapons while crouching and not sliding
  • Louder, bass-heavy bullet impacts on hits (possibly too much so)
  • Cheat modes – exploding bullets, extra enemies, floor lava (just damage over time when you’re on the ground), Mario mode, tough citizens
  • A whole lot of console variables to customise just about every aspect of the mod. Want to slide longer? Wallrun faster (or slower)? Jump higher? It’s all configurable. Look in ep2_mobility/cfg/mobility.cfg.

Bugs Fixed:

  • driving the buggy over a cliff no longer crashes the game
  • fixed some near-clip problems when using high field-of-view
  • fixed mysterious rising into the air (if you started climbing, then turned away so that there was no space to move into, you would just keep climbing)
  • fixed voice lines in the tutorial being counted as music, and controlled by the music volume slider
