I wish they make a modern remake for this game. Amazing implementation of army building features and one of the most unique RTS games ever made! It is a bit basic in some of its RTS elements though.

As someone described it before, this game is a scissor vs rock vs bigger rock kind of game. Just build the biggest baddest creature and have fun!

Be the Sigma male you always dreamed of being. While that dream may be impossible these critters most definitely were not. This was a real blast from the past, and in my eyes Impossible Creatures still holds up as a gem even today. It is a grueling and brutal RTS where I always felt like I was on the back foot every single level, but when I finally managed to clear a chapter it feels so gat dang euphoric. The story feels like an La Noir mixed with classic action hero style drama, rife with tons of one liners and gags. While the endless waves of enemy critters beat me down I at least got to vibe to the sound track of "Rex is being attacked" and "Your critters are being attacked" Truly your goons do their job but not more because I cannot for the life of me manage 5 battle fronts at once while trying to build up a new outpost base while being besieged on all sides by massive goliath Wale Tigers. An absolute gem and I will always be glad to buy it again everytime.
