I’m going to veer off from the mechanics we want to see implemented to ramble on about something else that I desire in my game. Something big. Something impossible to ignore. Something that every mad scientist comes up with eventually.
Something that is dinosaurs.
Here is my proposal:
Science, being science, couldn’t resist the opportunity to start cloning dinosaurs. Since every scientist has seen Jurassic Park, they decided to put some safeguards into place, though. Sadly, they didn’t actually get the chance to before the zombie apocalypse hit, and one of the guys hit the “start automated cloning process” and “open all the doors” button in the lab before being eaten. The clones take a few days to fully mature, but once done, will be released and start pouring out into the world centered on the dinosaur cloning facility.
Some of the dinos are herbivores, and won’t be that aggressive, but will fight back if attacked, or if you go after their friends. They could make for a good hunting target, requiring multiple traps or big guns to bring down, but offering enough meat to sustain you for a while. Others, naturally, are tyrannosaurus and velociraptors. And not the scientifically accurate kind, either. No, the kind that will hunt you down, like wolves, but worse. Providing a spike in difficulty if you just hide out in the wilderness. Alternately, you could lure a t-rex into town and let it go nuts on the zombie hoards, thinning them out and taking down a dangerous predator in the process.
Zombies and dinosaurs may both be dangerous, but as far as they’re both concerned, the other one is a perfectly legitimate food source. If you just fade away and don’t make yourself too much of a target, they’ll go after each other and give you a nice escape. But, if you’ve managed to get stuck between two groups of them, you’re probably not going to get out un-eaten.
Gameplay wise, dinosaurs would provide a nice spike in difficulty with a powerful enemy type that wanders around. It adds some options for the player, but also gives an enemy that operates on different rules from the mindless zombies. Raptors will avoid traps, compys will move in fast swarms and actively try to surround you, and tyrannosaurs will tear down buildings to get to you. They hunt more by scent than by sight, and have a lower vision range. Their attacks do more cutting damage, making cutting armor more useful than against the zombie hoards. Also, they’re fast. Often faster than you.
That’s what I’d like to see.
