I also have the super earth edition disc, the DLCs are already in the disc, you can see all those DLCs in the stratagem page and main weapon page even without redeeming the code, I haven't redeem the code also. But this so claimed ULTIMATE COLLECTION actually does not contain terrain and precision specialist DLC, they showed up with blue color lock and is only unlocked when I bought the terrain specialist online. If you chose to redeem the code, please share here what you got, because others told me the code is for digital download of ps3 and vita which I don't have, plus a theme for ps4 only.

PS Plus free game supposedly only work when our PS Plus subscription is still active, I wondered if the game will continue to be playable if we bought add-ons only to be added to the base free game when our subscription have lapsed? I think this is the type of game with very high replay value and worth keeping for good 

I hope the developer would follow up with additional expansion in the form of 4th alien world or more exotic monsters to blast. This is my second favorite action game after Earth Defence Force
