Action Thexder 1

Thexder is a hyper dual-armor robot-jet transformer. Armed with heat-seeking lasers and touch-controlled flight mechanisms, Thexder is the ultimate fighting machine. There is only one Thexder in existence, and you are the proud pilot at its control. Be careful! If disaster falls upon your vehicle, there will be no replacements, and your mission will be terminated.

The game will start you off at the left of every level, and your mission is to make your way to the exit-point on the right side. Along the way, you will find enemies blocking your path. Shooting them will use up some of your energy, but some enemies replenish energy when killed. Usually there are more than one way to reach the exit, and it's up to the player to figure out the optimal path.

Along the way, it's possible to find power-ups that will ensure you will have additional energy at your disposal. Completing levels also increases your maximum energy level.

Originally developed and released in 1985 by Game Arts for the NEC PC-8801, Sierra On-Line ported the
game to DOS, Apple and Tandy systems in 1987.
