Invasion Protocol Valuation: 8/10 Mainly a bullet hell roguelike, top downish shooter Positive + Multiple characters with unique abilities and starting weapons + Different abilities to switch on the go + Different weapons with different play styles + All items are random excpet the ones that are call in by radio, but also those are from a random selection + Very addicting gameplay, has something very appearling for me + Maps increase difficulty gradually so you can adjust your self with obtained items + good audio tracks Negate - Start with only 2 unlocked chars, each difficulty you unlock more types that can be very hard - because its random, some maps, can spawn only a certain type of enemy that can be very tough - some menus could be a bit more intuitive, may a button to always show the radio items we can see them without opening the whole panel The game is very good for quick runs and probably better with friends, can play 4 players on the same screen, I could only test with 2, a keyboard and gamepad. Gotta wait for my buddy for it.

Frenetic, challenging and very addicting, better in coop but also enjoyable single player, you start shooting newbie enemies , they die really fast, as you progress in sectors it becomes much more interesting, very fun!

Very good game, judging by how simple it is, while being hard at the same time: Controls are good, the game is rewarding and punishing at the same time. Great local coop. BUT: I never managed to finish a run without a big-time freeze. And this is a total downer. The game doesn't require mentionable resources but still keeps crashing all the time. I've tried a few AMD Adrenaline settings to fix this but to no avail. And sorry: Why would I have to experiment around with graphic settings to be able to play a game that I've paid real money for? Edit: Switched to a 5-year-old laptop with no dedicated graphics card and the game fluently worked like a charm and is great. Completed it all and am looking for a sequel. So please leave your sophisticated graphics cards locked away because it might cause the game to crash. Thumbs down!!!
