Yeah I felt Titanfall, and I can see the Horizon too. If you had to pick one game its most similar to you'd say Destiny, but it definitely has other vibes too it. In no way is it just a shameless clone, or heavily inspired, like these BR games right now. It seems quite unique.I'm not saying it's cloned or heavily inspired.
Haven't played Destiny, so I can't compare, but I'm sure you're right.
