What is Slum Z?
If you're bored of standard tower defense and want something that feels like a fever dream, you need to check out Slum Z. It's a weird, gritty hybrid that mixes survival shooting with roguelike elements to create a stressful fight against the undead.
Gameplay
Forget everything you know about classic tower defense. You aren't just placing towers and watching them work like in Kingdom Rush; you're dropped into a gritty, third-person survival shooter. Your moment-to-moment loop is chaotic: you fight through zombie hordes, scavenge for rare cursed blood, and build defenses to keep the swarm from overwhelming you. It's a hybrid of a roguelike and an incremental game, meaning you'll spend a lot of time shooting and then using your loot to upgrade your arsenal for the next run.
That 'one more run' feeling is what keeps you hooked, but it's not all smooth sailing. Since it's an indie project, you'll run into some rough edges. The movement feels clunky at times, and the incremental upgrade side can start to feel like a grind. It's more about survival and mood than a perfectly balanced strategy experience. You're fighting for every inch of ground in a dark setting where every bullet actually matters.
At $11.99, it's a bit of a gamble. You're paying for a specific psychological horror vibe and a weird experimental loop, not a polished AAA title. If you're okay with a bit of unrefined gameplay in exchange for a dark atmosphere, you'll find it addictive. But if you're looking for a tight, balanced TD experience, the clunkiness might just frustrate you. I'd give it a 6/10—it's a cool idea that just needs more love to really shine.

Verdict
“a very decent zombie incremental roguelike game, it can keep you entertained and have some fun for a couple of hours”
Grab this if you love psychological horror and don't mind some unrefined, clunky indie edges. Skip it if you want a polished, balanced strategy game or can't stand a grindy upgrade loop.
