So many new guns added since launch. It's still a good game, even though the engine is extremely dated (and look every year past its expiration date). Fun to come back to once in a while.

This game is insane! A little hard to get used to the controls in the beginning but after that it's fantastic! Beautful looking, very colorful and vibrant, great sound effects... not...so great voice acting but you don't play renegade ops for the story.
Very arcadey, explosions everywhere, frantic missile dodge dancing, bulletspraying, great SHOOTAN. Quite challenging even at normal difficutly. All in all, well worth the money.

It's hard to recommend this game for its current full price of 10 euro. It's a little steep for the 3.5 hours it took me to finish the game. UNLESS you approach it like fine piece of chocolate or a drink at a super fancy restaurant or something. Yes, it's expensive but it is also high quality.
Get it if you like games like Braid and Machinarium.
