Outpost Siege: Hold the Core against the Night Horde

In Outpost Siege, you lead the Operator around the arena and protect the Core. This is one of the action games with automatic shooting at the nearest target. Aliens come to the base at night, and Scrap immediately becomes an experience.

How to survive the first night

The weapon fires itself, and you choose who to finish off first. Pick up Scrap to level up and take on new weapons or upgrades. The list includes blades, lightning, rockets, fire aura, shotgun and frost, and the right set brings the weapon to evolution.

What to build around the Core during the day

In the mornings, you place and upgrade turrets around the Core in limited slots - familiar from Crazy Tower Defend. Then you buy stratagems: airstrike, minefield and Core shield. Due to the small number of slots, each building changes its defense.

When does the boss come and where does the sector end?

Every fifth night brings a boss, and the tenth ends the sector with a final fight, similar to Doomsday Heros. If you hold the Core, a Daily Operation opens for each day. Alloys are used for constant improvements in the workshop, and the game also has six Operators, two arenas and 29 achievements.
