Beast Guardian is a 30-stage hero tower-defense campaign built around route construction rather than fixed tower pads. Place four ordinary animal soldier roles and seven WeightPlay heroes on a forest grid, keep at least one route open, and protect the crystal core through six five-stage regions. Wolves, armored boars, flying bats, regenerating packs, wounded sprinters, and eclipse formations ask for different defenses. Stages 5, 10, 15, 20, 25, and 30 end with rule-changing Bosses instead of ordinary enemies with larger health bars.
The crystal routes connect six parts of the Guardian Forest: the first root paths, crystal air lanes, Ironbark works, the regrowing mistwood, storm ramparts, and the eclipse road to the Voidroot throne. Enemy packs are trying to reach the core at the far side of each battlefield. A cleared stage means the route is secure long enough for the guardians to advance to the next sector.
You command the defense before and during every wave. Acorn Guards and Moss Shell Taro hold bends, Scout Archers and Moon Cap Orla cover long angles, Rune Sappers slow clustered attackers, Medic Cubs repair injured blockers, and heroes such as Spark Paw Fia provide focused damage. The board is not a decoration: every placed defender changes the route unless the unit is serving as ranged support away from the path.
Route building: defenders occupy normal ground cells. Enemies recalculate a path around them, but a completely sealed route makes ground enemies attack the nearest blocker until a route opens again. Flying bats ignore the ground maze, so a long route alone cannot solve every wave.
Combat roles: blockers buy time, Archers and Orla cover distance, Sappers apply splash damage and slowing, Medics heal damaged defenders, Fia focuses Boss pressure, and Gear Horn Rux strengthens nearby allies. Selecting a placed unit shows its upgrade cost and sell refund.
Wave information: before each wave, the HUD names the incoming wolves, boars, bats, escorts, or Boss. Non-final waves continue after a five-second countdown, so the player can read the next composition and use earned coins before pressure resumes.
Special enemies: Ironbark stages give enemies breakable guard armor; mistwood enemies recover health while moving; storm enemies accelerate after falling below half health; eclipse stages combine armor, recovery, surge behavior, flying routes, and reduced slow effectiveness.
Permanent progress: victories award stars, upgrade points, and Diamonds. Upgrade points improve hero power, defender health, or starting economy. Diamonds are optional and can confirm a core revive, reroll a result reward, or unlock a cosmetic golden defender frame; normal stage unlocks do not require them.
Stages 1-5 teach route bends, split lanes, early ranged coverage, boar pressure, and the consequence of sealing the path. Shadow Brute attacks blockers faster than ordinary Bosses, so the first finale tests whether the route has a durable anchor instead of only damage units.
Stages 6-10 introduce bats that fly across the grid and mixed air-ground waves. Forest Behemoth summons wolf and bat support after losing part of its health. Stages 11-15 add breakable Ironbark armor and finish with Ironbark Colossus, which rebuilds a large guard layer midway through the fight.
Stages 16-20 make unfinished enemies regenerate while moving; Verdant Ancient restores a portion of its own health and calls support. Stages 21-25 add wounded speed surges, ending with Tempest Ravager accelerating its escorts. Stages 26-30 combine every previous rule with reduced slow effectiveness. Voidroot Emperor has two phase changes, so stage 30 requires ground routing, air coverage, armor breaking, finishing damage, healing, and saved Boss focus in one defense.
Beast Guardian uses free placement because the central decision is not simply which tower to buy; it is how each body changes travel time, firing angles, and blocker risk. The five-second transition between waves preserves the feeling of one continuous defense while leaving a short planning window. Thirty stages are organized as six mechanical arcs so difficulty grows through new counters and combinations before raw statistics. Touch players use the same large build cards and grid cells as mouse players, while keyboard controls can move a tile cursor, build, select, upgrade, sell, cycle units, and start waves. This distinguishes the game from Animal Auto Squad: both reward preparation, but Beast Guardian lets the player reshape the battlefield and react during live waves.
