Breed is your pleasure, a cutting-edge science-fiction shoot-'em up, which skilfully blends addictive, accessible, free-roaming gameplay with cutting-edge, state-of-the-art technology to expand not only the gameplay potential, but also the player's perceived freedom within the game world. In other words: multiple 3D-Action. Why are they called Breed? 2602. The new colonies of mankind in the neighbouring Besalius binary star system were caught off-guard by an aggressive attack from a highly belligerent alien race which the Colonists nicknamed The Breed.
Even though the game itself is... Really badly made... The engine itself is an entirely different ordeal. To date I haven't seen any single game that is so easy to change - you can do a great deal just by editing the script .txt files, which are literally plain text. Not only this, just the way the engine works is very flexible, because in other engines you have limitations on what you can do.
In this case, I simply took Darwin's main turret and equipped it as a weapon for the character. The only other thing I did was change the location of the weapon grip, because otherwise the turret blocks the player's vision in first person (which is why the Assault Rifle looks like it's floating too).
Normally, such things are hard-coded in files you have no way of opening - or in the weapon grip's case, in the model of the character itself - but with BREED? It's all right there, available to be messed with.
It's such a shame the game wasn't good. If it were, and became popular, it may very-well have become one of the most modded games out there, but, alas, it wasn't meant to be I guess.
