Oh, and you can’t use any Infinite Ammo weapon unlocks, either! You are required to complete the game in the S Rank time, which is 3 hours 30 minutes for Leon A (1st) and 3 hours for Leon B (2nd), while also ensuring that you only save for a maximum of three times.
As explained in our guide to the various Ranks and Rank times, achieving S+ on Standard is no easy feat. To unlock the Resident Evil 2 Infinite Ammo Rocket Launcher, players have to earn an S+ Rank with Leon in the Standard difficulty mode. Needless to say, the Rocket Launcher is a beast, and it becomes even more beastly when filled with a limitless supply of rockets! Per its in-game description, it’s “a portable rocket launcher that can hold four 66 mm incendiary rockets,” and these rockets “unleash a powerful conflagration” upon anything standing in your way. Bestowed upon Leon by a mysterious ally, the ATM-4 Anti-Tank Rocket Launcher is the tool that ultimately defeats one of the game’s most powerful enemies.
The Resident Evil 2 Infinite Ammo Rocket Launcher will be the ultimate weapon of choice for most players.
