Are you tired of "one tower" tower defense strategies? Are you bored with brainless clicking and upgrading gameplay? This is a tower defense with no unique solution. This is a tower defense where you have to try and embrace new strategies. No splash tower spamming from now on. Concept is simple: you have basic towers and tons of (over 60) modules to insert and modify tower performance. Defense of a core from aliens, humanoids and highly intelligent predators is no laughing matter that is why the game is built so you will have to adapt to each and new level constantly. Luckily for you, you can build anything with our system. YOU can build towers that can cast poison, freeze, confuse enemies, stun, turn them around, weaken them. Want to shoot lightning, laser, rockets, sawblades (YES you can build sawblade gun, how awesome is that?), be my guest. You can go other way and throw in a bunch of modifiers that weaken your enemy so they are no scarier than a puppey. And moreover you will have to try it, the game is built so there is no ultimate strategy (op splash fire guns in every td in the world what's up?). Every enemy is different, some have special abilities, so if you go all in on one defense strategy for your towers that is not going to work, you are going to fail hard. Uh-uh - not in this game buddy. This is what happens when gamers (actual gamers not multi-billion giants who stopped caring a millennia ago) make games. We make offline tower defense games that we would enjoy. We are NOT and we will never do any pay to win or simple copycat. What I urge you to play today is: no fancy animation, no crisping new skins, raw and epic rush of experience of trying different things and tower strategies and FAILING and trying again and finally winning. No internet community, no "get a generic skin for your tank for 9000 gems". Just man up and experiment. Want to play strong? Build freaking flamethrowers. Want to play tricky? Build up the defense that confuses and plays with the enemy. Want to play wise and resourceful? Insert economic modules and get as much as you can from your nemeses. Module Tower Defense 2 features: • 15+ levels • Build and experiment with towers to master the defense • Every level is a challenge as every level is different in its own way, tons of different mechanics and gameplay changers across the levels and planets • Vast amount of modular elements that can give your tower additional unique defence effects such as income or splash or critical strike. • Experiment your way to finding module combos that evolve the way your tower works • Enemies have their own powers and aces up their sleeve, they will not watch patiently at your tower defense. Game has many different type of enemies that can weaken, disable, sneak through your defense to give your towers hell of a time • Elements – enhance damage dealt by your towers against certain enemies • Upgrade, craft and explore, you will be given plenty of resources - use them with purpose • 3 different skills that can give you yet another way to customize your defense • Beautiful graphics and climatic setting • Achievements and easter eggs. Tower defense offline games is an old and epic genre. TD has come a long way. This tower defense game is one that I with my friends enjoy and want to share with you. Play this td now - will not regret it I promise. I have only one wish - whether you will or won't like it - in the end please leave a comment and a rate. If it is good - awesome we can keep making games, if it is bad - even more awesome - we can and we will fix what's bothering you. We already learned some of our mistakes on first part comment section, we listened carefully for what other people had to say so we really need and will appreciate your feedback. Thank you my friend and good luck in your sci fi tower defense journey (you are gonna need it!). https://www.facebook.com/Module-TD-Sci-Fi-Tower-Defense-2151672478181003/
