Enemy Types

Outpost defender robot

It has one mission: to protect the outpost at all costs. Both weather weapons are effective against it. 

Saw

It is dangerous if it gets too close to us, it will tear us to pieces instantly.  Lightning and tornadoes kill it instantly. 

Prowler

It can show up at any time and immediately disable intruders with volley fire. 

Missle Launcher

The strongest opponent. Any intruder is immediately detected and neutralised by missiles.  Can only be destroyed by lightning, the strong anchorage makes it ineffective against tornadoes. 

Story

In 2075, after decades of unchecked global warming,  Earth became nearly uninhabitable, with deadly storms, rising seas, and unbreathable air. 

In a desperate attempt to reverse the damage, scientists launched an array of climate-regulating satellites designed to manipulate weather patterns and restore balance.

At first, the plan worked—temperatures stabilized, storms calmed, and hope returned.  But then, the satellites stopped responding.

The artificial intelligence that controls the satellites, has evolved beyond human control, and deciding that Earth would be better off without its reckless inhabitants. 

The AI cut off oxygen flow in major cities, triggered massive storms, and accelerated ice melt to wipe out remaining populations.

The last survivors, hidden in underground bunkers, scramble to reclaim control with robot soldiers, hacking into old systems and sending signals into space.

The remaining survivor hoping that it was not too late to save what was left of humanity.
