Strategy Tips
Place towers near path bends where enemies spend more time in range.
Freeze Rays are great support — slow enemies for your damage towers.
Snipers reveal stealthed enemies and deal huge single-target damage.
Tesla Coils deal double damage to shields at level 4.
Upgrade existing towers before spamming more — level 3+ towers are very efficient.
Coordinate with your partner! Cover different sections of the path.
Sell underperforming towers for 50% refund to fund upgrades.
Missiles stun enemies at level 4 — great against bosses.
