Review of Killing Floor 2 I've been a lover of wave based survival / horde shooter games for many years of my life. Killing Floor 2 has been one that's brought me some of the most fun thus far. Which is surprising to me, because I vividly remember playing it for the first time in 2017, but not really liking it. Until I was brought back into it a year later, and suddenly everything just started clicking positively for me. KF2 was my primary introduction to the series. Previously, I had played a very limited amount of the first game, but I'll take another look at that some time in the future. I feel as though Killing Floor 2 is a great entry point for anyone who's interested in either the series itself, or a fun Co-Op horde shooter. Blut, immer blut These games do have a narrative that runs in the background. Mostly told through bits and pieces of dialogue, and the levels themselves. However, my focus has almost always been on the gameplay, as that takes center stage. If the game's lore is of interest to you though, there's plenty to read about. Horzine's involvement, the experiments, super soldiers, and ultimately how we're not stuck in this apocalyptic situation. The tone of Killing Floor 2 is sort of a mix between serious, and comedic. Cheesy one liners while you're running about blasting Zeds into mist, and the way certain boss enemies will taunt you. The addicting loop of the game stems from its wave based "Survival" mode. Being a game of this type, it's extremely important that the loop facilitate replayability, and if possible, provide a dynamic structure to its gameplay. This was the first thing that got me invested into KF2. Every time you play, waves are never the same. Exactly what Zeds spawn, where, and in what quantities, is always randomized. The only predictable stages are the boss waves, but even then there's a pool of different bosses the game chooses from. Now through in the wide variety of different maps, large selection of classes (Called Perks), multiple difficulties, various secondary objectives that can pop up during a round, and you're always in for something that differs from the last attempt. Survival mode sees you trying to make it through the final wave, depending on your choice of length (Short, Normal, Long). Survival isn't the only mode here though. There's also "Endless". Which is exactly as it sounds. This is probably where I tend to spend most of my time these days. It goes on virtually forever, with a slight increase in difficulty as the waves progress. As an added bonus though, Endless introduces modifiers/mutations that can appear randomly. Such as putting you through a wave of only bloats or scrakes, giving Zeds ridiculously sized heads, making Zeds volatile so they explode on death, and many more. All while your friendly neighborhood Patriarch commentates your progress. Lastly, there's the somewhat newer "Objective" mode. This is the closest you'll get to a form of story gameplay. These have you following orders through a map, protecting zones, then moving to the next objective, until you reach the finale and successfully finish the mission. Fit with a fantastic blood pumping OST, and great visuals (Specifically the weapon animations). Throw in modding support, and there's even more to play around with. I feel it's important to mention that although it is designed as a Co-Op game, it does allow for solo play. The more players that join for Co-Op, the higher the waves scale in difficulty & Zed count. Solo players are capable of enjoying the entire game on their own, including the hardest difficult; Hell on Earth. Choices, Progression, & Dosh There's a lot of choice in how you take to defeating Zeds in the bloodiest way possible. KF2's classes, which are called "Perks", come in 10 different varieties. The unique aspect of them, is that each class corresponds to a specific weapon type & specialization (Providing unique buffs for self or party). SWAT, for example, uses primarily submachine guns & is built for clearly groups of weaker Zeds quickly. While something like Sharpshooter wields mostly large medium to long range precision rifles that do insane damage. Great for taking down elites or bosses. Now you can use any weapon on any class, but you would efficiently earn EXP while doing so, or gain any of the buffs that might apply to your weaponry too. Perks can all be individually leveled up. The max being 25 per. Every 5 levels grants you a special point that you can use to choose between two perk skills per tier. Once you've maxed a perk, it can optionally be prestiged. Unlocking a new fancy badge for it, letting you start the grind all over with a permanent EXP bonus, and giving you plenty of additional playtime. Dosh is earned from blasting away Zeds and completing optional objectives. It's used to buy any number of weapons, body armor, grenades, etc. It can also be shared amongst on members of your team. There's also many different characters to pick and choose from. They have no effect on gameplay, but can be fully customized with a huge amount of unlockable.. and purchasable.. cosmetics. A lot of cosmetics, such as pieces for your character, or paints for your weaponry, can be unlocked through general play with a random drop chance. Some can be crafted. Others can be obtained from opening crates, but unfortunately a lot of the cosmetics are locked behind paywalls & RNG. Such as needing to buy keys to open crates, just for a chance to get the thing you want. Or hope someone's selling it on the market for a reasonable price. I can't see 'em, but I smell 'em. (Complaints) Thankfully, my gripes with the game are relatively minor. The biggest issue I have with KF2 is the way that Zeds spawn. There's a huge amount of entry points in maps, like vents or holes on the boundaries, where they often come from. The issue is that.. they also just spawn out of thin air if you don't have line of sight. The amount of times I've started a wave, and spun the camera around to see a group of Zeds pop into existence two feet off the ground, or rounded a corner and watching a group suddenly appear, is frustrating. It also makes defending, or creating choke points, difficult. Because no matter way, if you stand still for two seconds, you'll get jumped from behind. It takes a lot of time to get use to the lack of a meaningful sprint. Every perk has different movement speed, so trying to sprint and watching your character move at a snail's pace is a bit frustrating. The knock back. Zeds knock you around constantly, if you get overwhelmed. This almost always results in being pushed into a piece of geometry with a hitbox ten times the size of its model, getting you cornered/stuck. Leading to a quick death. Lastly, less of a full complaint, and more of a warning, and that's the DLC. There's plenty of paid cosmetics, but there's also a fair amount of weaponry that's now locked behind a paywall. Normally, I wouldn't mind this type of thing, but the asking price for the weapons is ridiculous. $10~ for one single weapon is a bit much. Thankfully, you can buy the pass' which grant you all the paid weapons for much cheaper. Conclusion (Pros & Cons) Killing Floor 2 is well worth the investment for those that love wave based shooters. The game's bloody, detailed, and has loads to play around with. Pros: +Dynamic survival +High variety +Endless +Co-Op & Solo friendly +Steam achievements Neutral: ~DLC weapons Cons: -Enemy spawn behavior Disclaimer Thank you for taking the time to read my review. Please remember, that this is just my opinion. We don't have to agree, one thing I love you may hate, and one thing I hate you may love. Hopefully this gave you an idea of what to expect. Review lengths have been greatly compressed due to the character limit. 04/16/2026
