Outpost: Tower Defense

The Star Alliance has claimed a quiet little moon called Delta Six-Seven. The survey said it was empty. It was not — and the locals have a taste for cargo.

Outpost is a tower defense game about keeping your crates safe from the aliens on the moon. Build towers on the pads beside the path, upgrade them as the parts come in, and stop every wave before it reaches the outpost.

TWELVE OUTPOSTS, ONE MOON Turn the moon to follow the trail across twelve hand-built stops — switchbacks, quarries, a three-way split, a grinder, and a lean season where every part counts. Each level adds a new idea instead of just more aliens.

SIX TOWERS THAT EACH DO A DIFFERENT JOB

• Bouncer: turret that hits one alien at a time
• Fan: blows back aliens, deals a low amount of damage. Most effective against Gliders
• Goo: slows aliens, deals a low amount of damage
• Drill: slow but brutal — always goes for the biggest alien
• Relay: speeds up rate of surrounding towers
• Arc: lightning that hits multiple nearby aliens

AN ACTIVE ABILITY From Switchback on, the grab beam freezes a patch of ground for a moment so your towers can catch up. Charge it by downing aliens, then pick your moment.

A CAST OF TROUBLEMAKERS Grunts, Rollers, Luggers in cooking-pot helmets, Gliders that fly over everything, Splitters that become two, Menders that heal their friends, and the Hauler, who carries off a whole stack at once. Not monsters — just very determined thieves.

THE BRUTE HUNT Finish the campaign and a priority transmission arrives: something bigger has turned up, and it shoots at your towers. Track the Brute from stop to stop, then face it in its den for a three-phase showdown.
