How many GB is Thunder Tier One?

20 GB

That makes it bigger than 82% of Action games we have measured.

The median Action game needs 4 GB; the largest tenth start at 40 GB.

Leave at least 29 GB free: games need headroom to unpack updates.

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

Thunder Tier One is a realistic top-down shooter where you join an elite special operations team tasked with stopping a dangerous terrorist organization wreaking havoc across the fictional Eastern European country of Salobia.
