Seize control of enemy planets in this nostalgic space sim and tower defense game made in the style of classic Flash games. Start by dominating orbital space in starship combat with railguns, defense turrets, and shields. Once clear, land on the surface to build a base and destroy waves of enemies.

<h1>Current Development Status</h1>The Fortified Space Demo is now available! Thank you for the phenomenal level of interest and feedback you have provided so far.  The demo will continue to receive regular updates, driven by player suggestions, and the full Early Access version will be released in late 2025.  I am currently pivoting toward graphical updates, but I still have a multi-page list of cool features to add and I will be incorporating those over the coming months as well.  I hope this game scratches an itch of yours.  If so, feel free to wishlist! <h1>About the Game</h1><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3819710/extras/9b358b767ac49451319db9ceedb8ce0c.avif?t=1771305305" width=400 height=150 />As captain of a Unified Earth Forces starship, you are thrust into the heart of a counter-offensive against humanity's foes, leading daring missions deep into enemy territory. Fight in space and on the ground as you spearhead the assault, establish vital footholds, and pave the way for our Marine landing forces. <h2 class="bb_tag" >Build and Defend Planetary Fortifications</h2>Think strategically as you deploy barriers, turrets, gates, and barbed wire on the planet to safeguard the area against relentless waves of enemies.  Or, if it's been a long day, maybe you can just build a wall of turrets.  The enemy will get the message.  Create a secure zone to allow our Marines to land safely.  After reinforcements arrive and you've succeeded in your mission, you can get resupplied with unlimited materials to continue building in a sandbox mode.  Keep coming back to the planet to work on the base and fight off enemies!<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3819710/extras/63cc87337f38e0b3057565cee867250c.poster.avif?t=1771305305" width=654 height=368 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3819710/extras/63cc87337f38e0b3057565cee867250c.webm?t=1771305305" type="video/webm;
