On the cosmic frontier, humanity has fought alien species for a century. As traditional defenses fall to new-gen alien mechs, tech giant ShellMobile—human-centered at its core—kindles new hope via breakthroughs in extraterrestrial titanium ore research.

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 25 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
ShellMobile takes its name from the idea that tech—like a nut protecting its pulp—sees mechs, warships, and stations as life's shields. Upholding "Machines for humanity," the company developed the Titanium Rampart Defense System after titanium refining breakthroughs, forming the unbreakable Titanium Rampart Line against aliens.
Titanium Lifeline: Extraterrestrial titanium is humanity’s tech foundation. Players send miners to extract it for defense upgrades and mech production.
Titanium Rampart Line: 5th-gen alloy walls blend alien materials with quantum lattice tech, equipped with self-adaptive nano-repairs that instantly rebuild plasma-damaged structures and deploy antimatter against "Ether-Eater" flyers.
After a decade’s hibernation, aliens return with "Venomfang" ground mechs (plasma drills) and "Ether-Eater" swarms (gravitational maneuvering). As commander, players must:
Deploy Defenses: Install pulse EM cannons between titanium walls to intercept flyers.
Mech Strikes: Lead Nut Shell forces in "Dawnbreaker" mechs with antimatter missiles.
Resource Warfare: Dispatch agile miners for rare titanium, refined by the Titanium Matrix into:
Energy Crystals (super units), Nano Components (repairs), Quantum Blueprints (tech unlocks).
Unlock weapons like Titanium Railguns and Dimensional Shields to fend off the horde.

机甲很帅,还可以改色,就是建筑物没有描述,有些不知道造出来是干什么用的,需要优化改进一下
玩法更偏向塔防,敵人一波波地攻過來挺吃不消的,UI需要改進,建議直接像紅警那樣把二級菜單放出來,不然真的手忙腳亂。
这游戏不能无脑莽,地形利用很重要
策略型的机甲游戏,机甲内容再加点,要是有工坊就更好了。玩着还行,没事可以开一把。
整体色调是灰色调的,色彩风格比较冷峻,看上去有点压抑,要不试试换成更精致亮色的画风?
这价格还要什么自行车?内容量真的很足
好玩,爱玩,下次还买
