ACE gave the game a score of 969 out of 1000, describing it as "a gutsy, brainy, frantically obsessive shoot-em-up with strategic depth". They felt that "the tiny detailed graphics reach their peak with the perfectly animated Oids themselves, but are low-key enough to let you concentrate on the game's unrivaled action". They also praised the inclusion of a level editor as a bonus that increases the game's value for money.
ACE editor Andy Wilton concluded, saying, "some wonderful set-pieces and hellish crossfire zones make the game tremendously playable" and "the sheer intensity of addiction it generates will have you playing night and day (...) If you're sick of all those glossy, disposable ST shoot-em-ups, get Oids - it'll knock your socks off". Writing for
Compute!, David Plotkin highlighted the fact that "this game really shines in playability". He also praised the game's graphics and sound, calling it "a winner".
ST-Log noted that "there are plenty of surprises in Oids" and praised the game's intense action where "things pop up from underground to fire on you, and alien ships suddenly appear from any direction". They also praised the game's addictive nature with editor
Clayton Walnum concluding "the first time I sat down to play Oids, I started at about 11 pm. When I finally decided it was time to put the disk away, the sun was coming up. Need I say more?" The game was reviewed in 1988 in
Dragon #137 by Hartley, Patricia, and Kirk Lesser in "The Role of Computers" column. The reviewers gave the game 5 out of 5 stars. ==Legacy==
