Base Defense 2 unblocked is a tower defense sequel from Beedo Games where everything happens along a single battlefield: your fortress stands on the left, and wave after wave of hot-air balloons, armoured airships and giant mechanical spiders pushes in from the right. Around the fortress are empty mounting points marked "Touch here to deploy", and filling them is the whole strategy. Start with a dependable Gunner, then branch out into electric, freezing, poison and toxic turrets that slow down or chip away at whole groups, plus close-range strikers for the heavy hitters that make it to your walls. Scrap metal from wrecked enemies pays for new units and upgrades mid-battle, while coins earned from finished missions unlock stronger weapons and bases for the campaign ahead. Every unit can be levelled up, repaired and boosted, and a Speed Up button lets you rush through the easy waves. If you enjoy it, take on the original Base Defense or the balloon-popping classic Bloons Tower Defense 4.
Everything is done with the mouse or a tap. Click an empty platform to open the weapon card, then click the card to deploy it; click a weapon that is already on the field to upgrade, repair or boost it, and use Pause or Speed Up in the top corner to control the tempo. In the first missions, pour your metal into upgrading one or two strong units instead of scattering cheap ones everywhere - a levelled Gunner covers far more of the road than two fresh ones. Once you have the metal to spare, place a freeze or electric turret in front of your damage dealers so enemies stay in range longer. Keep an eye on each unit's health bar and repair before it breaks, because rebuilding is always the more expensive option. Hold the boost for the biggest enemies in a wave, and only fast-forward when you are sure the current defences can handle what is coming.
