Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 4 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Ja,. Tower Defense macht süchtig! Dieser spezielle Kandidat ist besonders gefährdend. Es kommt keine Langeweile auf, weil es Knackig ist. ;D
It is a great game to relax and spend some good time especially because it is not so difficult yet is engaging.
+Tower Defense +Deck Construction +Campaign and rogue like mode +Over 500 cards (with some unique) -Not great for repeated plays -Rogue like mode isn't very hard This is a really unique take on tower defense and deck construction. This is listed as deck building, but it's really deck construction. Deck building is more adding cards to your deck as you play the game, while Cartridge Defense you make a deck before you start a map. Between maps you can modify your deck with new cards you've unlocked before you start the next map (think along the lines of how Hearthstone works). Overall I had quite a bit of fun playing this, and enjoyed the deck construction aspect of it. Each map is different and sometimes your deck needs to change to be able to beat the challenge. There is a good selection of cards (over 50) with some legendary and rare ones that really are quite unique. The campaign was really 20-30 hours long for me, at which point I unlocked all of the cards and beat all of the maps. After that you can try the roguelike mode, which was fun for a play but wasn't really challenging enough to keep me going back for more. My only con is the game doesn't really have the legs for repeated plays. Once you unlock everything and beat the campaign, you've just about seen everything you need to see. Still recommended for anyone who is a fan of tower defense.

Very cool Tower Defence with Deckbuilder elements, Retrowave ambiance, and most important of all, it has Mazing. It also works on every potato PC out there.
[strike]I would love to recommend this game to people but I can't do that when the tutorial is completely bugged. It gets stuck when it tells you about the bosses.[/strike] The tutorial bug seems to have been fixed, and that bug was the only reason that I initially gave the game a negative since I quite like the game.
A very fun Tower Defense + Card Game mashup. There's a good variety of towers, and the way cards combine and buff towers really keeps things fresh, instead of just placing the same old stuff every time. Planning out decks is super fun, and the ability to save many different decks is really nice. The card sorting UI is ok, you can filter for type or rarity with the search, but it's a bit clunky editing decks that are already full. I wish there was a line-of-sight overlay so I could see which of my towers were obstructed and which are not. Tip: blocks are not solid (maybe platform would be a more accurate name), so towers behind blocks can still shoot unobstructed. [u]Update:[/u] I've beat endless and roguelike modes. Endless wasn't that interesting, having all the cards made it pretty easy, and the performance tanks hard on later waves. Roguelike was extremely fun, having to work my way through a set of levels with random buffs and cards. Overall I had a great time with this game. Solid game highly recommended if you're a fan of both TD + CCG.
tl;dr: Nice little tower defense game, definitely worth it when on sale. Full price.. ehhhh. Review is as of 100% achievement unlocks. + The theme and the way the UI works into it are pretty cool. + No goofy things like upgrading mid-wave or calling new waves early (your taste may vary, but I hate that crap in the more popular defense games). + Deckbuilding is alright, with a decent variety of cards. - For as good as the music is, there's only a couple of tracks, so you get kind of sick of them by the end, - The railgun sound effect is absolutely obnoxious, and you're going to be using them a lot later on. - The UI's fanciness means that sometimes you're hyper-focusing on one quarter of the game window since the cards and control panel take up so much screen real estate. - The roguelike mode doesn't really have much to shake things up to have you wanting to come back once you've completed a run. I enjoyed it and don't regret the time I put into it, but I'll probably be putting it away now unless I feel the need to go chasing wave 120 in endless mode as a personal challenge.
This is a maze tower defense. You can put obstacles in the enemy's way, and they move around it while finding the fastest path to the exit. I love this. The hours you see are two days of play. A mix of a tower defense and card battler. So many different cards that are truly unique and fun to play. Highly recommend. This is the tower defense game you have been looking for.
Smooth game play, and awesome sound track that doesn't get repetitive after playing for a few hours.
