What the developers have to say:

Why Early Access?

“Exo TD has been in development for over a year and continues to grow into a fun and unique entry in the tower defense genre. Through many rounds of community playtesting and lots of excellent feedback we've arrived at a polished and very stable foundation to move forward with.

Our main focus is providing our players with a great experience, expanded content will be delivered throughout the course of the Early Access life cycle. With the currently available content and planned content we're now ready to bring Exo TD out to everyone. Your support is needed to help grow and polish Exo TD beyond it's original scope. We look forward to sharing our vision with you all.

*Please note that this game is currently CPU intensive, systems with lower end or older processors may experience some performance slow downs while many objects are on screen. Fixes to address performance on a wider variety of systems are in the development pipeline and are expected to be delivered before the end of Early Access.”

Approximately how long will this game be in Early Access?

“The game foundation is currently very stable on modern systems. Our intent for Early Access is to provide players with a fun and unique experience while we continue to expand the game and review community feedback to help improve and deliver on all of our players expectations.

New features, content, and balance are the priority right now. When the game feels complete and matches our vision we will release the full version, our current estimate is this will take 6-12 months. We hope you'll stick with us through this process so we can give the best possible user experience.”

How is the full version planned to differ from the Early Access version?

“At a minimum we plan to more than double the amount of available content including base turrets, satellites and upgrades available from Early Access launch. New campaign scenario options will be available including 4 planned scenarios each with multiple challenging bosses, further improved adaptive and reactive AI tactics, a new endless mode, custom wave modifiers and more feature content is planned.

Throughout the Early Access process and well into release we hope to improve on all aspects of the game, from adding new content, scenarios, gameplay modes, UI/UX, SFX, VFX, and performance improvements across all supported systems.

**(Each Scenario session is expected to take 2-10+ hours to fully complete with no prior scenario knowledge. A scenario takes approximately 30-45 minutes for completion start to finish).”

What is the current state of the Early Access version?

“The current game version features 2 unique fully featured campaign scenarios, a roster of 5 standard turrets each with 6-8 unique upgrades across 3 upgrade tiers, and additional shield, resource, and utility defensive options. As development continues new turrets, satellites, defenses, game modes, and feature content will be introduced via patch cycles.”

Will the game be priced differently during and after Early Access?

“The price will not increase after release from Early access.”

How are you planning on involving the Community in your development process?

“The community is a vital part of our development process and your support is very appreciated. We hope to deliver an enjoyable experience and welcome community suggestions and feedback which will help shape this game.

Expanded Arsenal Patch 1.0 Released!

Expanded Arsenal Patch 1.0 has been released!

This patch is the first of several major planned content updates. We're introducing 6 new turrets, each with many upgrades options.

- New Game Modes: Endless Invasion

Endless Invasion: Enemy forces will continuously spawn to attack, gradually spawning faster, stronger, and better ships. This mode will keep score and allow you to more easily try out strategies in a faster pacing than the scenario modes.

(Note: This mode is still heavily in balancing, significant performance updates will be included in the next major patch, the performance results will largely dictate overall design balance moving forward.)

- Six new baseline unique attack type towers, each with multiple upgrades.

- Gamma: Focuses strong gamma beams at enemies causing them to accumulate radiation, taking damage over time. Can stack twice, each hit refreshes the effect, deals additional damage and extends the max duration.

- Arc Reactor: Energized particles run through the conduit producing high voltage electrical arcs that can attract and arc to nearby targets. Deals randomized damage, arcs to 2 additional nearby available targets.

- Artillery: Fires heavy ballistic shells that explode on impact dealing additional damage in a small radius. Explosion damage based on distance, fires at random targets.

- Gauss: Rapid-fire rounds, fires at nearest target. Has a 50% chance for projectile to ricochet to a nearby target.

- Rail: Energy is concentrated to propel a specialized heavy projectile to enormous speeds. Deals heavy damage with a 25% chance to ignore armor and shields each shot. Requires a significant cooldown period between each shot.

- Comm: Satellite-ground communication has been established, relays power and provides a bonus to satellites depending on type. Extends shield satellites max duration by 10 seconds.

New upgrades:
Gamma II: Max radiation upgraded to 3 stacks. Improved recharge rate and damage.

Gamma III: Max radiation upgraded to 4 stacks. Improved recharge rate and damage.

Saturated Gamma: Can fully penetrate ships allowing for an unlimited potential for radiation damage. No stack limit. Each stack increases damage and causes permanent radiation damage over time.

Gamma Burst: Focuses targets already afflicted with gamma radiation. Causes the target radiation effect to burst for damage equal to 2x the total potential remaining damage of the existing radiation effect.

Gamma Burst II: Focuses targets already afflicted with gamma radiation. Causes the target radiation effect to burst for damage equal to 3x the total potential remaining damage of the existing radiation effect.

Irradiate: Intensified beam of radiation that focuses critical ship systems. Enemy ships drop additional scrap after beam duration is completed. Additional scrap based on % health remaining for unit type.

-Arc Reactor-
Arc Reactor II: Arcs to up to 3 additional nearby targets.

Arc Reactor III: Arcs to up to 4 additional nearby targets.

Arc Cannon Tether: Two energized fields are each launched at a random nearby target. When both fields reach their targets they form a connection dealing increasing damage over distance.

Arc Cannon Tether II: Increased damage and fire rate.

Arc Cannon Chain Reactor: Arc fields now briefly chain to all available nearby targets in a small radius from the impact location.

Penetrating Shells: Increases damage and fire rate, has a 10% chance to deal 2x impact damage to the target. Each additional shot against the same target adds +5% chance.

Penetrating Shells II: Increases damage and fire rate, has a 10% chance to deal 3x impact damage to the target. Each additional shot against the same target adds +10% chance.

Explosive Feedback: Enemies caught in and destroyed by the initial explosion also explode themselves.

Gauss II: Concentrating fire allows each consecutive shot to deal slightly more damage each hit on the same target. 50% chance on hit to ricochet to a nearby target. Fires at nearest target.

Recoil Rounds: Specialized projectiles that ricochet more frequently. 75% chance on hit to ricochet to up to 2 nearby targets. Fires at nearest target.

Satellite Communications II: Targets satellites and provides a bonus effect. Shield Satellites: Each charge adds 20s to max duration.

Signal Hack: Attempts to hack vulnerable enemy ship systems. Disables flight and forces ship targeting systems to lock on and attack nearby enemy ships.

Many minor bugs and fixes have been addressed this patch.

Whats Next?
Many planned turret upgrades did not make it into this patch, these additional upgrades are coming soon to be delivered by minor patch on a much quicker release cycle.

The next major patch will add many more upgrades and will feature the addition of expanded satellites into the game.

Major performance improvements!

Revised Scenario balance.

and more.

Thank you for playing Exo TD, we look forward to showing you much more of what's to come!

About This Game

Exo TD is a game similar to traditional tower defenses with new core experience changes. The setting takes place in fully 3D space as you take control of your planet defenses. With your resources you must construct turrets, shields, orbital defenses, and more maintaining your Planetary Shields as each invasion force and it's flagship boss arrives.

In the standard mode invasion forces will periodically spawn in waves to challenge your grip on the planet, on successfully penetrating your Planetary Shields your planet and all its defenses will be lost to them.

Each wave features an increasingly difficult set of AI ships that will challenge you with new tactics, strategies, and reactive combat abilities. Destroyed enemy ships will often yield drone collectible scrap resources, providing opportunities to upgrade your turrets into newer more powerful models augmenting their defensive capabilities to deal with the increasingly powerful threats.
