Axiom Verge is the Metroid/Castlevania/Contra/etc inspired action platformer developed by Tom Happ. The premise is that you control Trace, a scientist who was hurt and then wakes up in a mysterious, advanced, and horrifying world. The more you progress the more equipment you obtain. The world begins to open up to you. It feels as if a ode to games of old that provided that feeling of isolation to a diverse point.
