Installation instructions

Sonic: Lock & Load is a Sonic the Hedgehog-based platforming-focused first-person shooter on the GZDoom source port, i.e. a DOOM semi-total conversion that requires DOOM 2's IWAD.

It's not really based on any kind of Sonic game in particular, instead taking inspiration from the entire franchise.

Sonic: Lock & Load is inspired by the entire Sonic the Hedgehog series of games, Sonic Robo Blast 2, DOOM Eternal, various GZDoom mods and various classic FPS games.

Sonic: Lock & Load is a project by Arsalan Kazmi, free software under the 3-clause BSD license.


Chaos (1.x)

Version 1.4

Future release

Sonic: Lock & Load v1.4 is a major update, bringing new levels, new techniques, refinements to the changes made in 1.3.x and major changes to the gameplay and Sonic: Lock & Load's fundamentals.

How many times have I said "welcome to the next level" anyway?

Really? Only three? Funny, seemed like more.

Note: There's a lot more stuff than all this. I just don't want to list it all...




Classic Sonic


More to come! Sonic: Lock & Load v1.4 is still in development.

Version 1.3.3

Sonic: Lock & Load v1.3.3 is a minor update, containing some changes to the game's fundamentals and balancing.

Version 1.3.2

Sonic: Lock & Load v1.3.2 is a semi-minor update.

Version 1.3.1

Sonic: Lock & Load v1.3.1 is a minor update involving mostly bug fixes.

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.

Version 1.1

This is basically v1.0.1. Man, I wish I knew about proper semantic versioning when I released this...

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.
