They're "already fulfilling re-orders" for the 'what if' shooter from Kaos. It has an "excellent multiplayer experience" and they're plugging in more servers.
"We are delighted with first day sales for Homefront and are already fulfilling re-orders for the game from multiple retailers," said THQ president and CEO Brian Farrell.
"Homefront's excellent multiplayer experience, combined with our commitment to dedicated servers, make this a must-have purchase for gamers," added Danny Bilson.
"Due to the strong and growing demand for Homefront's multiplayer, we continue to add dedicated server capacity. We are confident that the large-scale multiplayer maps featuring 32 players, vehicles, infantry and drones, will continue to be a major draw for the huge audience of FPS gamers looking for a new experience over the coming months."
Homefront releases on Xbox 360, PS3 and PC tomorrow in Europe.
