How many GB is Sentry?

3 GB

That is less than the typical Shooter game, which needs about 8 GB.

Leave at least 9 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Sentry is an action-defense first person shooter where you defend your spaceship against a relentless alien threat. Use traps, turrets and environmental destruction to repel invading hordes and engage the enemy in fast-paced FPS action across a dynamic singleplayer or co-op campaign.
