Frontier: Siberia — this is a captivating tower defense game set against the backdrop of a catastrophe in the Soviet era. At the secret facility «Object-31», the containment of a mutagenic virus failed, and now it's spreading through the taiga, turning wildlife into infected creatures headed towards the station. You, as the last surviving engineer, must construct defenses from salvaged equipment and hold out until evacuation arrives.
The game offers:
* 10 types of towers: from a machine gun nest and flamethrower to an EMP cannon, sniper, and plasma battery;
* 12 types of enemies and bosses: infected wolves, armored bears, flying ravens, regenerating boars, a giant mammoth, and a swarm queen;
* strategic synergies between towers: freeze + kinetic, radar + sniper, tesla + crowd control;
* 90 levels across 9 chapters with increasing difficulty and bosses;
* a global upgrade system powered by crystals, allowing permanent enhancements to all towers;
* daily challenges with unique conditions;
* scientists' diaries that unfold the story of the disaster;
* leaderboards for total stars.
How to play
Objective: prevent infected creatures from getting to the «Object-31» station. Foes advance in waves along the route — your task is to protect the base with the help of towers.
• Place towers: select an available spot and choose a tower from your arsenal (or vice versa — pick the tower and then the spot). Each tower requires coins to build.
• Earn coins by eliminating enemies — use them to construct new towers and enhance existing ones during the fight.
• Tap on a deployed tower to upgrade, sell, or relocate it.
• Press «Start» to initiate a wave; ❚❚ to pause, and 2× to accelerate time.
• Ensure the base's health bar remains above zero throughout all waves. The higher the remaining HP, the more stars you'll earn (up to 3★).
• Stars and victories earn you crystals — use them in the global upgrade tree to boost every tower's power.
