This is my favourite out of Adamant's latest releases. Sky-Tyrant requires only the Savage Worlds main rules to play (in my case that's the Explorer's Edition) - so it's a good purchase if you're "just curious" about the MARS Savage world setting, and are not ready to commit to buying the main rules book. Its scenes rush forward into each other with the excitement of Star Wars or Indiana Jones. Pre-generated characters also help greatly in implementing the setting, which is just about generic enough to not require the core settings book. This adventure jumps from straight-forward encounter survival to being part of politics (but still with action). Sky-Tyrant is for the more "cinematic" action favouring players. The accessibility of the scenario means that it is also perfect for conversion to other systems (or maybe different settings). Summary: Fast-action pure-pulp sci-fantasy, awesome!
