| Dusekkar | DPS | Powerful unit with excellent damage output and versatility across different game modes and situations. |
| Tower | Role | Why A-Tier |
|---|---|---|
| Hyperlaser Sniper | DPS | Amazing alternative to S-Tier DPS units, deals great damage, budget option that can carry games when combined with support towers. |
| Bling Boxxer | Support | Excellent support tower and great starter option, provides valuable buffs and utility for early to mid-game progression. |
| Sniper | DPS | Excellent long-range unit for supporting main DPS, great for weakening high HP enemies but less effective against crowds or low HP targets. |

|---|---|---|
| Pistoler | DPS | Decent mid-game unit if you don't have better options, performs adequately on most maps but outclassed by higher-tier units. |
| Paintballer | DPS | Good high-placement unit with decent damage output, situational but can be effective in specific map layouts. |
| Flamer | DPS/Crowd Control | Decent unit for crowd control but there are generally better options available for most situations. |
| Freezer | Support/Crowd Control | Not the best support unit but the freezing effect can be useful in specific situations, particularly against fast enemies. |
| Tower | Role | Why C-Tier |
|---|---|---|
| Windforcer | DPS | Basic beginner unit, should be replaced as soon as you acquire better towers from higher tiers. |
| Bloxxer | DPS | Another starter unit with limited effectiveness, prioritize upgrading to better towers as you progress. |

The SFOTH (Sword Fight on the Heights) event requires specific coordination and strategy:
Wave 1-3: Player 1 rushes Pyromancer to level 3, Players 2-5 spam level 2 Minigunners
Wave 4-7: Player 1 finishes Pyromancer upgrades and places support towers, other players continue Minigunner spam
Wave 8-10: Player 1 adds Freezers and additional Pyromancers, other players expand to new areas
Wave 11-12: All players focus on upgrading existing towers and preparing for the final boss waves
Boss Strategy:
Tix can be earned by completing waves, defeating enemies, and redeeming codes. Focus on completing higher difficulty modes for better Tix rewards, and consider using a Tycoon tower to generate additional income during matches.
For beginners, start with basic towers like Scout and Minigunner to learn mechanics, then work towards acquiring S-Tier towers like Mage and Noli. Helper Bot is also excellent for beginners as it significantly boosts your other towers' effectiveness.
The Gravekeeper boss requires strong DPS towers and proper positioning. Use Mage or Noli for high damage, supported by Helper Bot buffs. Make sure your ranged towers are placed on elevated surfaces with good line of sight to the boss's path.
Game modes vary in difficulty, wave count, and boss encounters. Easy mode has 35 waves with one boss, while Insane mode has 68 waves with multiple bosses. Higher difficulty modes offer better rewards but require stronger tower combinations and strategies.
S-Tier towers can be obtained through the summoning system using Tix. The drop rates are low (especially for Heroic and Legendary units), so save your Tix and summon in batches of 10 for better chances. Some S-Tier towers like Mage may also be available through special events or quests.
Yes, you can play solo, but some content like the SFOTH event requires 5 players. Solo play is great for learning mechanics and farming resources, while multiplayer offers unique challenges and rewards.
New codes are typically released during game updates, events, and milestone celebrations. Follow the official Twitter and Discord to stay updated on the latest code releases.
Insane mode requires optimized tower placement, S-Tier units, and proper resource management. Focus on building a strong economy early, acquire top-tier DPS units, and use support towers to maximize their effectiveness. Coordinate with teammates if playing multiplayer.
