About game
Frontier: Siberia is an atmospheric tower defense set in a Soviet-era science disaster. After a containment failure at the secret station "Object-31", a mutagen virus spilled into the taiga — infected wildlife now waves toward the station. You are the last surviving engineer: build defenses from scavenged gear and hold the line until evac arrives.
Inside:
• 10 tower types — from a machine-gun nest and flamethrower to an EMP cannon, sniper and plasma battery;
• 12 enemy types and bosses: infected wolves, armored bears, flying ravens, regenerating boars, an overgrown mammoth, a swarm queen;
• tower synergies: freeze + kinetic, radar + sniper, tesla + crowd — real tactical depth;
• 90 campaign levels across 9 chapters with rising difficulty and bosses;
• a global upgrade tree paid in crystals — permanently boost every tower;
• a daily challenge with special rules;
• scientists' diaries that reveal the story of the disaster;
• a total-stars leaderboard;
How to play
Goal: stop infected creatures from reaching station "Object-31". Enemies come in waves along the path — you defend the base with towers.
• Build towers: tap an empty pad and pick a tower from the arsenal (or pick the tower first, then the pad). Each one costs coins.
• Coins drop from kills — spend them on new towers and upgrades during the battle.
• Tap a placed tower to upgrade, sell or move it.
• The "Start" button launches a wave; ❚❚ pauses, 2× speeds up time.
• Keep the base health bar above zero through all waves. The more base HP you finish with, the more stars (up to 3★).
• Stars and wins grant crystals — invest them in the global upgrade tree to strengthen every tower.
