Is Outpost: Infinity Siege worth it?

Outpost: Infinity Siege is worth it if…

  • you like games that mix shooting, building and strategy in one loop
  • you enjoy a grind that pays off in a fortress you built yourself
  • you want a co-op game where the whole squad defends one base
  • you like runs that play out differently each time, with difficulty levels to climb

A gun you build, not just find

Your XEN Firearm is the one weapon that grows with you. Its protoslag attributes change what it does, and different ammunition types change it again: one load burns, another freezes, another punches through armor at range. The same gun plays differently every run, so deciding what to feed it is a real choice, not a menu chore. It matters, because the machines in the Signet surveillance area do not wait politely. When a wave closes on your outpost, you are out there with them, shooting while your turrets work the flanks. The weapon feels like the heart of the game: one tool, endlessly reconfigured, in a world that punishes a dull edge.

Your outpost is your build

Everything starts with scavenging. You explore ruined zones, gather resources, and merge and upgrade outpost units into a fortress of your own design: more turrets, better layouts, heavier guns. The outpost fights with you, so a well-planned base does half your shooting while you handle the rest from the ground. Fair warning: the early game is lean. It takes a long grind before your outpost looks like the fortress on the box, and players who want instant firepower may bounce off that stretch. But there is a real payoff in watching a base you assembled piece by piece shred a horde you would once have fled from.

Better with friends on the wall

This is a game built for a lobby. You and your friends can take on Recovery Day together, or hole up in Endless mode and see how many waves of monsters you survive before the last one falls. Coordinating matters: someone holds a corridor, someone feeds ammo to the guns, someone calls out the flank before it becomes a problem. The shared loop of looting, building and defending gives a group plenty to argue about and celebrate, and a wave that would end a solo run becomes a close call you all walk away from. Sessions are easy to join and built around jumping in together.

Questions before you play?

Can you play it solo?

Yes. The game supports singleplayer alongside co-op, and the core loop of exploring, building your outpost and defending it works alone. Solo players should know the early hours are the slowest part: your outpost starts bare, and it takes time and resources before it fights well on your behalf. If you can bring friends, the defense missions get livelier, but nothing in the game requires a group.

What is the XEN Firearm?

It is your unique signature weapon. Instead of swapping guns constantly, you customize this one: protoslag attributes give it different properties, and different ammunition types change its behavior again. The idea is to keep deepening one weapon rather than cycling through a pile of them, and to adapt its setup to the enemies and difficulty level you are heading into.

What do you actually do in a session?

A session usually splits into two halves. First you explore a zone, gather resources and harvest outpost units, choosing your path and how deep to push. Then you bring the haul home, upgrade and rearrange your outpost, and defend it when the machines attack. The exploration mode offers multiple difficulty levels and distinct maps, so runs vary, and Endless mode condenses everything into pure survival against wave after wave.
