You lift the cover of the red button and press it. Suddenly, your chair is rocketed up and out of the 'mech's shattered body.
Shortly after you eject, your battered 'mech begins to glow, and soon after explodes in a blinding wave of light.
The two 'mechs turn and begin walking away. On the horizon, you can see the flashes and glows of battle.
The static in your helmet stabilizes enough for you to make out bits and pieces of the conversation. It's the central command operator from whomever you're fighting for ordering a full retreat whilst the surviving pilots argue and resist.
You touch down softly, the parachute on the ejection seat slowing your fall enough to be survivable.
The chair has some light survival rations, a map of the general area, and a knife.
Also on the chair is some sort of transmitter. It emits a regular "beep". it's hard-bolted into the chair, so no hope of getting it loose and carrying it with you.
Wait behind rocks for a search party to come nearby since the beeping on the chair was probably a homing beacon. When a search party comes nearby, use the radio to describe the search party and see if it's friendly. If the radio isn't two way, try to identify them if possible by the color scheme of the people versus the two mechs that shot you before.
