Sony has reminded players that Monster Hunter Freedom Unite has today been added to the North American PlayStation Plus Instant Game Collection.
Monster Hunter Freedom Unite is a PSP title boasting "over 500 hours" of gameplay, with over 1,400 different weapons and 2,000 armour sets.
Players can form teams of up to four and play local co-op multiplayer as they try to defeat the game's trademark massive monsters.
Sony has also reminded US gamers that the PS3 version of Tomb Raider and the PS4 title Dead Nation: Apocalypse Edition will be leaving the Instant Game Collection on April 1, meaning players will have to download both games before that date in order to keep playing them after their removal from the service.
Earlier this month, Thomas Was Alone, Lone Survivor: Director's Cut and Unit 13 were also added to the US Instant Game Collection.
European PlayStation Plus subscribers also had five games added to the Instant Game Collection in March - Dead Nation Apocalypse Edition, Tomb Raider, Brothers: A Tale of Two Sons, Pixeljunk Monsters Ultimate HD and Smart As.
Sony has yet to confirm April's batch of Instant Game Collection titles.
