As a professional game developer I disagree with most of your comments.

This code is clearly not perfect, but the from what I've seen, this is something I could work with.

- Function names are easy to read and understand. - Indirections are kept to a manageable level.

Not going to lie, playing Crysis was a lot of fun, and I never knew this was the underneath function running it.

Crysis shipped with a full blow SDK that included most of its source code. You could actually rebuild the game from it, the 50MB dll that controlled the whole game.

Old players maybe remember that the crysis multiplayer was the most cheated game in its era. It was totally unplayable due to all the cheating and that killed the game.

One way to make cheats. You could load up the SDK in visual studio. Find the code that's removing -1 ammo when shooting and edit it to not do that (most of the physics and game logic was editable that way). Compile the DLL. Replace the original DLL in the game directory.

Was ammo in Crysis controlled client-side? I've always assumed such counters were stored server-side and thus a server won't apply a "fire" event if the player's ammo counter is at zero until it receives a "reload" event to reset the counter.

Almost everything was controlled client side, including collisions and kills. There was one cheat for sale for example that ruined the game, you'd join a server and all players would be automatically killed every 10 seconds.

I remember experiencing that actually. Just random damage every few seconds. Is there any reason why the "don't trust the client" mindset is not used in games despite it being accepted in web development?

The game was released in 2007, Windows XP era. The very idea of security was being discovered.

One explanation I’ve seen about weak server-side verification is online multiplayer is a cost center so developers wants to offload much as they could. At least before microtransactions I guess.

If I can recall it was even easier than that. There were so many "trainers" available that would give you infinite energy etc. Even easier than that, I remember one hack was to basically just drop an XML file in the game directory to give yourself the ol' reliable freezing pistol hack.

Good game though, I think Crysis 1 multiplayer is to this day one of the most fun multiplayer games I have played. After Crysis 1 they really CoD'fied the game, which is a shame. That and BF2142, A-plus games.

Looking forward to Crysis Remastered, hope they don't screw it up.
