SteamSiege is a tower defense game created by Frogoworks, inspired by games such as Ironhide's Kingdom Rush and PopCap's Plants vs Zombies. Players take the role of a general in the army of Rimal, a steampunk kingdom located in a large desert known only as "The Great Expanse", defending several key locations across the kingdom from invasion by a variety of hostile monsters and invaders.
The basic gameplay of SteamSiege is fairly simple - enemies run along a path toward the end, yielding Cogs when defeated. Cogs can be used to purchase towers, which can be placed in any position along the track. There are a variety of towers, which are unlocked over the course of the campaign. Each tower has two "core" upgrades, then splits into two diverging paths, which each have two upgrades, allowing for customization in the upgrading of towers. You lose when your heart count, starting at 20, is reduced to 0
Enemies come in waves, spaced apart by a couple seconds to a minute, and ramp up in difficulty the further one gets into a campaign. Some enemies are armoured, taking less damage from non-Magical attacks. Others are poison or freeze your towers, or are resistant to magic. At the end of each "world" is a boss, which is stronger than the other foes.
Some levels have gimmicks, such as prebuilt towers where you can buy mercenaries, services that can be purchased from inventors and magicians, fixed hazards that fight towers and foes or even areas you have to spends Cogs to clear out. The difficulty ramps up throughout the game, as Cogs become scarcer and the wilds become fiercer the futher you get from Rimal's capital
Despite being a relatively simple game, there is a lot of strategic depth inherent to the genre and this is carried over into SteamSiege, with the huge variety of enemies and towers allowing for all sorts of situations to arise, requiring a mix of quick thinking and planning to get out withall your hearts intact.
See SteamSiege/Towers for information on the upgrade paths
|Musket Garrison||With a high speed of fire and deadly aim, the Musket Garrison is the most reliable and most revered of the Rimali army's towers. Equipped with the latest in firearms technology, Muskets are the main damage dealers for the first part of the game, combining with the Automaton Barracks to create powerful defenses for very cheap||90 Cogs||Starter|
|Automaton Barracks||Small factories that create automated soldiers powered by steam, Automaton Barracks are the foundation of a good defense. Although they may not be the strongest, Automatons are amazing at stalling enemy attacks so your more offensive-oriented towers can get in damage, and pair with Musket Garrisons to create a simple yet effective defense||80 Cogs||Starter|
|Tesla Coil||Magical conduits that send out arcing bolts of electricity, Tesla Coils are the most basic form of magical tower. Although their base damage output is rather low, there is a high chance for Tesla Coils to do a critical hit, which deals almost double damage, and they are able to completely ignore armour, making them a more specialised tower||120 Cogs||Starter|
|Frost Sprayer||The Frost Sprayer is an experimental design, created by the eccentric inventor Kalura Jacksaw. Shooting out a highly concentrated blast of cold air, Frost Sprayers shoot slowly but their ammunition is powerful - it freezes in place any foes (or friends) unlucky enough to be caught in the blast, allowing your other towers to get in a lot of damage||200 Cogs||Beat 1-4|
|The Incinerator||The Incinerator is the latest design from the top military scientists, launching hefty fireballs onto the path, dealing splash damage to multiple foes at once. The Incinerator is a high damage tower, pairing well with stalling towers such as the Frost Sprayer or the Automaton Barracks, and being useful against swarms of low health enemies.||150 Cogs||Beat 1-7|
|Steamshudder Behemoth||An enormous tank mounted in place, slowly shooting high damage shells that explode in a small radius. However, at any time you may pay 300 Cogs into the behemoth. If you do, it rises up and becomes a huge tank, which slowly trundles around the radius, crushing any foes in their path and gunning down most others, until destroyed by attacks, at which point it reverts to tower form||250 Cogs||Beat 1-12|
See SteamSiege/Enemies for a list of all enemies
Enemies in SteamSiege are primarily the minions of Jhaila, a rogue steam mage who abandoned the teachings of the Iron Mistress, the god of Rimal, instead serving the mechanical demon Chronos. While at first the enemies are only lowly automatons and bandits, the closer they get to Jhaila's unholy citadel the more dangerous the foes get. Enemies work how you would expect them to work - they run along the path, fighting with any units stationed there, aiming to reach one of the exits. Some wear armour, being resistant to normal attacks, while others are immune to magic, meaning that arcane attacks don't work on them.

|Rimalia||Rimalia is the heart of the nation, and it's fertile valleys fuel the armies under your command. Containing the capital city and the surrounding oasis, Rimalia is the first area in the game and the easiest, with the player only contending with the raiding parties and bandits under Jhaila's command. The boss of Rimalia is Big Mickey, one of Jhaila's key lieutenants and the boss of the various bandit gangs that prowl Rimalia's outskirts.|
|Silent Dunes||The Silent Dunes were once a prosperous, if not booming, area under Rimal's control. However, since the rise of Jhaila their harvests have failed and the bandit presence has increased significantly. To the south, near the border, the dark necromancer Shef'kei, the world's boss, has been gathering power, sending her army of undead minions to slowly take over the province and claim it for Jhaila, who she serves under.|
|Lake Of Tar||
The Lake Of Tar is located just outside of Rimal's borders - a once great oasis, a center of trade and connection between Rimal and the other nations in The Great Expanse, the Lake was the first to fall under Jhaila's control, with demonic powers turning the oasis to tar and muck. The Lake is where difficulty really starts to ramp up, and the player faces all sorts of strange, demonic enemies, including the area's boss, the malicious devil Rhikaal
|The Unholy Lands||The Unholy Lands are a forsaken place, and the followers of the Iron Mistress are traditionally forbidden from entering the demon lord's cursed domain. However, due to the peril facing Rimal, an exception has been made, and now the player must journey toward Jhalia's citadel, and face the dark steam mage themselves. The enemies in The Unholy Lands are strange fusions between machine and monster, and the dificulty is extreme, much harder than anything seen beforehand.|
- It draws heavy inspiration from the newest game in the Kingdom Rush franchise, Kingdom Rush Vengeance
