Deathtrap

Got this accidentally ( essentially free with the cheapo van helsing bundle sale ) and was pretty surprised overall. Theirs skill trees for individual towers, a character you can move around and click and use skills with aside from your normal towers, and certain gear drops actually change your character cosmetically. Their is a bit of grinding this game will have you do, but no complaints.. its pretty cool and grinding just means more entertainment. Only thing i dislike the most is you cant pick and choose where to place towers, they are premade per map and you can just build them where the devs allow you to, but each tower has skill trees and you get skill points from leveling up so its not as bad as it sounds.

9.5/10 coop, 7.5/10 solo. I've many hours played outside of Steam as well. Fantastic tower defense & action RPG hybrid that allows you to customize your experience by focusing on towers ("traps"), or your hero, or both. There are really fun possibilities like tanking or freezing enemies on top of ground traps or creating synergies between your traps and hero skills. Better with coop as many maps are easier with 2 people covering 2 sides of the map and focusing on different damage types.
Pros:
- Many viable playstyles and trap combos
- Good sound design
- Some unique traps/towers I've not seen in other games before
- You have lot of control over your hero's progression through skills & gear
- Game speed and text scaling options available
- Traps can't be destroyed, so you don't have to worry about keeping them alive or repairing them like in Orcs Must Die or Dungeon Defenders
- Addictive
- One of the best coop games I've ever played. Great for a coop partner who isn't a hardcore gamer, but there's enough to keep them entertained if they are
- $1.99 is a great deal for this when it's on sale
Cons:
- Only 3 heroes, though they do each have a number of directions they can go in
- You can't fully choose where to put traps, but this becomes less of an issue as you enable and buy upgrades for them since they become very strong. At least the locations are always in the enemy lanes and there are usually far more than you'll actually use
- No matter what Steam controller settings you use, the game will always only launch with controller defaulted until you unplug it

Awesome co-op that keeps you coming back. Rewarding progression across weapons, armor, and skills. Devs did a great job adding variety to each tier of the campaign, making the same map play completely different each time. Bosses also present difficult surprises right when you think you're safe.
I recommend WASD for movement.

one of the most underrated games i ever played. it has a whopping 10 daily players but you can also play it solo (its actually kinda easier due to how economy works) played it with a friend trough radmin vpn (has vpn in name but its literally just better hamachi and thats all) and the game was stable af, literally no disconnects or any problems.
generally it was nice, will play more and remommend for that price, you can alos get keys to this game for like 1 euro .

Review
I received this game due to purchasing the neocore franchise pack. I did not really look into this game prior but apparently its an evolved version of the absolutely boring tower defence mode in the van helsing games.
Gameplay
You pick between 3 classes who can all build the same traps on specific spots or upgrade them. Those classes have own perks and abilities. Like enhancing specific traps or endorsing a specific playstyle. The sorceress seems to focus on slowing down enemies so you can kill them with your magic, hunter focuses on ranged combat and poison damage while the mercenary is supposed to be the guy who actually stays in the line and attacks the enemy.
This works to a certain extent really well. With also having a coop mode you can improve and synchronize certain playstyles. Ontop of that you can enhance your abilities with level ups and equipment you can find. In that regard it plays like a very regular arpg. In the earlier levels I feel the difficulty is just right. You can adjust difficulty and add new mutators etc. Levels itself are all different due to their setup therefore one tactic won’t work for every map and every character. In order to make it not tedious you can speed up time in increments making enemies walk faster, slower or pause.
There are some issues as some of the lategame maps tend to drag on, especially map design wise it’s a lot like van helsings “ink” world which I absolutely hated, felt unimmersive and uninspired. There is also no kind of storyline to bind these levels together so gameplay fatigue can hit in if you are absolutely not having a blast with the gameplay. Also it can be a bit buggy, many achievements don’t work, internet connection can be sloppy and a last enemy in a wave can stop spawning.
Story
There is none really. Defend the monster gates and don’t let the monsters reach yours. There is supposed to be some kind of story which is loosely connected to van helsings canon due to recycled enemies and the ink but it doesn’t offer a storyline per se.
Sound
Your characters shout some voicelines but not too many to make it interesting. The music is okay, sound effects and whatnot but it does not matter as its one of these games you play while having a podcast or youtube video on your second screen.
Conclusion/TL;DR
It’s a decent game. It has a unique arpg + tower defence idea and pulls it off. It doesn’t have any memorable story to set it apart. Its just a simple neat game nothing more and nothing less. There are better TD games out there but if you specifically look for an ARPG and TD mix this one is alright. Plus coop.
Decent Tower defence with arpg elements that is held back by its very average design and a few bugs here and there.

(Before anything, know that the game doesn't have an epic ambiance like in the trailer, nor visuals like on the pictures.)
If you love tower defense, go for it.
I wish the upgrades came faster though. After many hours, I still didn't unlock many skills.
A little disappointed to see my laptop's GTX1080 dropping fps with graphics settings on Very Low... I played other more recent games in Ultra without any fps drop.
If Deathtrap 2 comes to life, please optimize something.

A magnificent blend of diablo style rpg elements and tower defense. Similar to games like sanctum, but with more in depth character development part that includes talent trees for both traps and your character, crafting, equipping, shopping, co-op and more.

I wish i knew the game was this good when it released so i could have supported it back then.
Fills me with sadness that due to its niche nature it was dropped before even DLCs could have been released for it.
Still, functional, fun and if you wanna max it out, it easily cover 20-40 hours of gameplay.
