It’s a stand alone project building off of the 2001 build’s leak, trying to turn it into a completed game.
The download includes the leaked original content as well if you want to compare. The original content isn’t really playable as anything but novelty, since it’s more like the skeleton of a game than a game. The project has made strides in all aspects to turn half finished, often unpopulated locations into actual game levels. Pigcops are back, Duke’s model is improved, more voice acting included, level design with scripted encounters. Lots of stuff.
I found the first one was hampered by so many forced racing and card games as bottlenecks to progressing. Those would have been fine as optional side activities, but making them so mandatory really killed the pacing when it came to doing some shooting.
The bosses were super underwhelming. You had one giant boss where you were trapped in a small building and shooting up at him. Very uninteresting. The final sequence of the game felt like there was going to be a boss. Narratively the enemy headquarters are built up as being heavily defended, the bad guys are built up to be doing crazy genetic engineering, and the game gives you a last minute BFG. Then you get inside and it’s a bunch of reskinned low level enemies. Felt like the devs ran out of time or something.
In the shooting, the game did give tons of gadgets and options, though I rarely found myself using most of them.
I wish the sequel had built on the promises of the first game, but it basically turned into a generic shooter that cribbed the aesthetic from Borderlands.
Fallout 1 absolutely does it as well. Even the animated dialog the Overseer gives is different, as he gets frustrated with the dumb player character.
One of the more famous Fallout 1 dumb events is that the first super mutant in the game, who is guarding the water chip, will grunt back and forth with the player and then step aside allowing the player to pass by.
More like level 3 bandits appearing out of the woods and smugly threatening to mug me when I have armor made by a dwarven hellsmith and am holding the sword of Dragon Agony.
The bandit looks at me and thinks “Yeah. This guy is going to get it.” as he brings up his rusty shiv.
I’ve heard Homeworld Emergence (formerly Homeworld Cataclysm) is quite good. It started as an expansion pack for the first game but kept expanding until it was a standalone game.
