As part of their partnership with Amazon, Twitch.tv made its Prime service free last year for subscribers to Amazon Prime. Owners of the latter could now link their accounts with the former, unlocking all the bonuses of Twitch Prime, which includes a free subscription to a channel of their choice and a wealth of additional free content. The most recent of these rewards is a free copy of action-adventure game Titan Souls.

Considered by some to be the Dark Souls of 16-bit games for its high level of difficulty, Titan Souls was called "an obstacle course of mechanically challenging boss battles," by IGN, who awarded the indie game a score of 8/10.
Other titles made available through Twitch Prime have been horror games The Walking Dead: Season One and Oxenfree, as well as in-game loot for NBA 2K17.
Titan Souls will remain free of charge until May 24. Those interested in linking their Amazon account to Twitch.tv can find more information about Prime bonuses and discounts here.
