Command a UGA heavy cruiser against the Krellan Empire. Navigate space, manage resources, and coordinate defense strategies. Use starbases and outposts to protect colonies while engaging in tactical ship combat. Your decisions will determine the fate of sectors in this military space simulation.
Command the mightiest vessel in the United Galactic Alliance (UGA) fleet - an advanced heavy cruiser designed to be the last line of defense against the ruthless Krellan Empire. As a captain, you'll navigate treacherous quadrants of space, managing critical resources and coordinating strategies to defend your regions, plot tactical jumps through contested territories, and engage in intense ship-to-ship combat against the Krellans and their Zaldron allies. With the aid of your starbases and planetary outposts, defend against the relentless Krellan invasion force to protect your vulnerable colonies. Your strategic decisions will determine the fate of entire sectors in this deep space military simulation from Interstel Technologies.
*Star Fleet Deluxe (SFD) *is a strategic space war game. At the helm of a United Galactic Alliance (UGA) Invincible class heavy cruiser, you are tasked with defending the UGA colonies against advancing Krellan forces, and driving them out within a given time. Though the task is formidable, you are not completely alone. The surviving UGA starbases and outposts on unconquered planets will assist you in providing shelter in orbit, resupplying your cruiser, and providing real-time updates on Krellan movement
Though the concept of a timed space defense war simulation may seem simple on paper there is much depth to*** Star Fleet Deluxe***. Missions are randomly generated with Krellan battlecruisers, supply ships, and destroyers programmed to support one another in their invasion. Though they can be unpredictable, they maintain the same mission: conquer planets, attack UGA starbases, and ambush your cruiser at every turn.
Star Fleet Deluxe (SFD), developed by Trevor Sorensen and published by Interstel Technologies, has had a lengthy development history that spans several decades. While the game never saw a conventional commercial release, its development nearly reached completion in 2002 with the Beta version. The project's journey began in 1998 when Brett Keeton approached Sorensen about creating an updated Windows version of Star Fleet I - The War Begins! for internet distribution as shareware. Keeton, along with programmer Mike Hartman, initially focused on improving the graphics and sound of SFI. However, after realizing the original gameplay might not meet modern gaming standards, they decided to revisit Dr. Sorensen's archived X Version, leading to the creation of Star Fleet Deluxe (SFD). This new iteration, while sharing DNA with ***Star Fleet I ***through their common Starfleet ancestry, was specifically developed as an enhanced version for the MS Windows.
The game went through three iterations: the X Version from 1981, which was a FORTRAN-based rewrite that never saw public release; an Alpha Version in 1999 that received limited playtesting distribution; and the ***Star Fleet Deluxe ***Beta Version from 2002, which was nearly complete but needed final polishing and a few minor bug fixes. There was also a mobile version of Star Fleet Deluxe released, ***Star Fleet Deluxe for Android, ***available on the google play store from 2014 to 2021 which was derived from the SFD Beta Version.
Unfortunately, the chief programmer, Brett Keeton, passed away in 2002 and his code was lost. What we are releasing here is the Beta version (now designated Version 1.0) which, although it has some known minor bugs, it is fully playable to completion.
To help players unfamiliar to the Star Fleet franchise navigate this complex simulation, the game offers two learning paths: an in-depth officers manual for those who want to understand every detail, or a quick-start guide for those eager to jump into action.
Venture forth with the new capabilities within Star Fleet Deluxe under the MS Windows OS, with this call to action, engaging in battle with the Krellans should be much more entertaining and gratifying.
Star Fleet Deluxe takes place during Galactic War II, where the vengeful Krellan Empire (allied with Zaldron Empire) seeks to destroy the United Galactic Alliance (UGA), led by Earth. The game puts you in command of an Invincible class Heavy Cruiser as humanity's last hope against the Krellan invasion.
As the fourth installment in the acclaimed Star Fleet series, set between Star Fleet I - The War Begins ! and ***Star Fleet II: Krellan Commander ***in the Star Fleet series, which also includes the planetary invasion game Star Legions. The Krellans have progressed from using single destroyers to deploying battle fleets including battlecruisers, destroyers, and supply ships. Players must protect colonies and starbases until UGA reinforcements arrive, while facing both Krellan ships and cloaked Zaldron vessels.
The game represents the second wave of a three-phase Krellan invasion, bridging the gap between initial scout encounters and the full-sca
