Reviewing the Atari 2600 game, A reviewer in
The Video Game Update noted the game was challenging, writing that most players will accidentally blow themselves up with the dynamite charges before getting used to avoid them. The review went on to praise the games graphics, noting that they were similar to those of
Pitfall II: Lost Caverns particularly liking how the recued person waves at the player when rescued. A review in the British magazine
TV Gamer gave it straight four out of five scores for value, graphics, sound and gameplay calling it "an excellent game."
Lou Hudson of the
Fort Worth Star-Telegram opined that the game "isn't a bad action game, but appears to be out of a past generation. A year ago, it would have been excellent. This year, it's a little blah." In a review of the ColecoVision port,
Electronic Games wrote, "Activision has wisely used the superior graphics of the CV units to provide a breathtaking underground panorama," and concluded, "Congrats Activision!
H.E.R.O. is a real champion." Reviewing the game for the
Commodore 64, Bob Wade of
Personal Computer Games noted it was far more action-oriented than any of the mining-themed games as of late, while his fellow critics Chris Anderson and Peter Connor stated the game did not have state-of-the-art graphics for the home computer, it was still very enjoyable and challenging. In the June 1987 issue of
Zzap!64,
Julian Rignall wrote—of the C64 version—"
HERO looks awful, sounds terrible but plays absolutely beautifully." The Japanese magazine reviewed the game for the
MSX, declaring it to be a really fun game that fit the system perfectly. The review specifically praised the narrative, play control only finding the characters not strong. In his series in
Computer Gaming World on the history of Activision in 1987, Charles Ardai said that titles like
H.E.R.O. and
Park Patrol (1984) "don't exactly encourage kudos, but at least, they are unique." From a retrospective review in
Computer and Video Games,
H.E.R.O. was praised for its colorful graphics while concluding that the addictive gameplay made it one of the best games for the Atari 2600. Brett Weiss included the game in his book on the top 100 console games released between 1977 and 1987. Weiss wrote that the game made you "feel like a real adventure hero [...] a rare feat in the pre-
NES era of gaming." In their list of the top 25 Atari 2600 games, Stuart Hunt and Darran Jones of
Retro Gamer listed
H.E.R.O. as the second best Atari 2600 game. The writers declared that the game mix of action and exploration made it "a truly outstanding release" that was "beautifully designed, with bold detailed visuals and sound effects." ==Legacy==
