Welcome to Sonic: Lock & Load!

Sonic: Lock & Load is a Sonic the Hedgehog-based first-person shooter on the GZDoom source port, currently a mod that requires DOOM 2's IWAD.
Sonic: Lock & Load is free software under the 3-clause BSD license.
It's not really based on any kind of Sonic game in particular, instead taking inspiration from the entire franchise.
It's also currently very unfinished, and development is kind of slow.
Sonic: Lock & Load is a project by Arsalan Kazmi.
Releases
Chaos (1.x)
Version 1.3.3
Sonic: Lock & Load v1.3.3 is a minor update, containing some changes to the game's fundamentals and balancing.
- Increased Shuriken Crossbow damage output and end frames.
- Both Eclipse Blasters' knockback has been significantly reduced.
- Increased Piko Piko Hammer damage output.
- Chaos Emeralds won't replace soulspheres or megaspheres, instead only replacing the BFG9000.
- Chaos Energy will now rapidly decrease in Dark or Hyper form instead of deducting 2 at once. This is more of a visual change.
- The amount of energy you get from capsules is now reduced if you're in Super, Dark or Hyper form.
- Chaos Rings will now give you extra Chaos Energy if transformed (2 for Super, 4 for Hyper and Dark).
- Fixed an issue where the Recoil Burst would still cost Chaos Energy when transformed.
Version 1.3.2
Sonic: Lock & Load v1.3.2 is a semi-minor update.
- Sonic can now wall jump.
- The option for Slot 4 weapons to replace Slot 2 weapons has been removed.
- Fixed an issue where completing Green Hill's boss was impossible.
- Directional inputs for Sonic Thok and Chaos Snap now work with controllers.
Version 1.3.1
Sonic: Lock & Load v1.3.1 is a minor update involving mostly bug fixes.
- Skill 5 (Blue Streak/Thorned Rose/Fun is infinite/All Fail Shadow) no longer gives enemies double health.
- Fixed an issue where finishing a level as Shadow would end before the victory jingle played.
- Fixed an issue where Classic Sonic's mugshot wouldn't change when finishing a level.
Version 1.3
Finally, a REAL update!
Sonic: Lock & Load v1.3 (which can be considered the real v1.1 but we won't get into that) adds an all-new Green Hill, a redesigned Station Square, new abilities and way more.
We're getting closer and closer to SRB3...
Well, what are you waiting for? Download it now and experience the next level! ... Whatever that means.
This is normally the part where the changelog would go, but it's massive, and I'm lazy, so... just go to the GitHub release page.
Version 1.2
Like with v1.1, this is basically v1.0.2.
- Homing Attack improvements.
- Spin Dash improvements.
- Removed the Light Speed Attack.
- Pickups have been made fullbright.
- Added a new entrance to the Side Levels.
- Code cleanups and bug fixes.
Version 1.1
This is basically v1.0.1. Man, I wish I knew about proper semantic versioning when I released this...
- Added the Spin Dash for Classic Sonic.
- Added persistent control hints in each characters' tutorials that make learning the controls easier.
Version 1.0
It's been a long, rough road, but we're finally here.
The long-awaited first release for Sonic: Lock & Load, the Chaos Update, is finally out!
So without further ado... Welcome to the next level.
The Chaos Update is a turning point for Sonic: Lock & Load, becoming more than a simple DOOM mod some bored guy threw together after watching Peter Knetter videos.
Full changelogPre-releases
Dark (0.9)
Sonic: Lock & Load's Dark Update adds Shadow the Hedgehog! It's time to go and find that damn FOURTH Chaos Emerald!
- Added Shadow the Hedgehog.
- Added a taunt command which can be bound in the GZDoom settings.
- Caliburn now has a rotating attack outside of Super Sonic.
- New mugshot sprites for Amy.
- Hammer Jump is now triggered by crouching and pressing primary fire.
Rose (0.8)
Oh boy! The Rose Update! This is probably the greatest addition to the mod in ages.
This update marks the project's name change from 'Sonic the Hedgehog in DOOM' to 'Sonic: Lock & Load'.
This was done:
- as both a reference to His World from Sonic '06
- because I didn't want Sonic the Hedgehog in DOOM (or Sonic DOOM) to be confused with Sonic Robo Blast 2, which is what most people think of when they hear "Sonic DOOM" (which didn't work at all, even YouTube thinks S:L&L is SRB2)
Here's the changes:
- Added Amy Rose.
- Renamed Sonic's Eclipse Blaster to the "Eclipse Blaster Mk. V"
- New mugshot sprites for Sonic.
- Nerfed the Speedy Shotgun.
- Removed the tutorial.

Sonic the Hedgehog in DOOM's Ascension Update grants Sonic a revamped Boost that lets him ascend! (hence the title)

Eclipse (0.6)
- Added the Eclipse Blaster.
- Changed how the Speedy Shotgun works.
- Drifting now recharges Chaos Energy.
- Weapon pickup messages now reflect Sonic's reactions.
Knight of the Wind (0.5)
