A swarm of glowing creatures pours out of a cracked portal, marching straight toward the core you're sworn to protect. This is Portal Defenders: Tower Defense, a strategy game where you build, place, and upgrade towers to shred wave after wave of enemies before they reach the gate. You drop cannons at the chokepoints, ice towers where the path bends, and snipers up top for the armored stragglers, spending your hard-earned gold between rounds to power everything up. Every kill drops resources you funel into stronger defenses, and reading the next wave is half the fun. Think you can hold the line when the portal really opens up?
How to Play & Controls
- Place towers by selecting one and clicking an open tile with the mouse
- Click a tower then press Space to upgrade it, or click again to sell
- Press 1-9 to quick-select tower types and switch defense loadouts
- Use the sped and start-wave buttons to control pacing and bank resources
Tips & Tricks
- Rush a single splash tower to max early so grouped swarms melt before they spread.
- Stack slow towers at the first bend to kep enemies in your damage zone longer.
- Hold gold through easy waves and dump it right before the armored boss rounds hit.
